ASoC: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

ASoC: da7219: Use clk_round_rate to handle enabled bclk/wclk case

For some platforms where DA7219 is the DAI clock master, BCLK/WCLK
will be set and enabled prior to the codec's hw_params() function
being called. It is possible the platform requires a different
BCLK configuration than would be chosen by hw_params(), for
example S16_LE format needed with a 64-bit frame to satisfy certain
devices using the clocks.

To handle those kinds of scenarios, the use of clk_round_rate() is
now employed as part of hw_params(). If BCLK is already enabled
then this function will just return the currently set rate, if it
is valid for the desired frame size, so the subsequent call to
clk_set_rate() will succeed and nothing changes with regards to
clocking. In addition the specific BCLK & WCLK recalc_rate()
implementations needed updating to always give back a real value,
as those functions are called as part of the clk init code and a
real value is needed for the clk_round_rate() call to work as
expected.

ASoC: da7219: Expose BCLK and WCLK control through CCF

For the purposes of platforms which use the codec as DAI clock
master for the CPU and other codec devices, there is the need to
not only expose the clock gating of BCLK and WCLK but also the
ability to set those rates without going through the ASoC APIs.

To make this possible, the previous CCF implementation in the
driver has been extended to separate BCLK and WCLK out. WCLK is
the parent clock to BCLK, and is also the clock gate for both.
BCLK in HW is a factor/multiplier of WCLK so derives from whatever
SR is chosen for WCLK, hence the need to make it a child of WCLK
for the purposes of CCF. Enabling/disabling either BCLK or WCLK
will result in clocks being ungated/gated accordingly. To simplify
matters, these clocks can only be configured if the codec is set
as master, otherwise CCF control is disallowed.

ASoC: da7219: Update TDM usage to be more flexible

The previous implementatation was restrictive with regards to
BCLK rates for slave mode where the driver would not allow rates
the codec couldn't provide itself as clock master. The codec
is able to automatically determine and handle whatever rate is
provided so this restriction isn't necessary for slave mode. The
code was also flawed with regards to setting of the frame offset
as using rx_mask to explicitly set the offset has the knock on
effect of impacting the min and max channels for the codec, in
soc_pcm_hw_params() through the call to
soc_pcm_codec_params_fixup().

With this update, the driver now only limits frame size if codec
is clock master, and dynamically determines the BCLK offset
relating to WCLK using the tx_mask for slot offset along with the
slot width provided.

ASoC: da7219: Fix HP detection procedure for all MCLK frequencies

Currently when HP detection procedure runs for certain MCLK
frequencies, when PLL is bypassed, the procedure will incorrectly
report Lineout instead of Headphones due to timing incosistencies.
To avoid this problem, the PLL is temporarily enabled (if currently
bypassed and MCLK present) to provide consistent timings for the
procedure, regardless of MCLK frequency.

ASoC: da7219: Connect output enable register to DAIOUT

da7219 output (for headset capture) should be set to high-impedance when
not in use, since it will otherwise interfere with output from other
codecs attached to the same DAI.

ASoC: da7219: Improve pop/click performance for sensitive HPs

Currently on some headsets slight pops can be heard during DAPM
power-up/down. This can also be witnessed during the HP detect
procedure. This patch addresses the issue by adjusting DAPM power
sequencing slightly, the introduction of delays and use of
minimum HP gain to avoid such noise artefacts.

ASoC: da7219: fix inappropriate condition statement

Sparse reports a below warning.

sound/soc/codecs/da7219.c:804:57: warning: dubious: x & !y

The line includes a condition statement; '(a < b) & !c'. Practically, the
evaluated value of this statement equals to the value of '(a < b) && !c'.
Although, it's not an usual way to use bitwise operations as logical
operations to several conditions.

This commit fixes the bug.

ASoC: da7219: Disable AAD if codec is not a wake-up source

Currently if AAD is enabled in the device, during system suspend
the feature remains, regardless of whether the codec is a wake-up
source or not. This means some additional power is being used
which is unnecessary, and can causes issues with some platforms'
IRQ handlers where state changes during system suspend aren't
captured.

This patch updates the driver to disable AAD during suspend, if
we're not a wake-up source, and then re-enables this on resume.

ASoC: da7219: Reset codec gracefully, if still active

Currently the reset code in i2c_probe only resets the AAD part of
the device and not the entire codec. This patch updates the driver
to resolve this and ensures that if the codec is still active from
a previous boot then the audio paths are powered down prior to
reset.

ASoC: codec duplicated callback function goes to component on da7219

codec driver and component driver has duplicated callback functions,

register timing. This was quick-hack, but no longer needed.
This patch moves these functions from codec driver to component driver.

ASoC: da7219: Make more efficient use of MCLK within driver

Currently, if the driver has control of MCLK then it remains
enabled as long as the codec is in STANDBY or above. The MCLK is
only really required in STANDBY when a 3-pole jack is inserted
and the HP detect procedure is required to run.

This patch updates the code to enable/disable the MCLK when moving
between the STANDBY and PREPARE bias level, and when a 3-pole jack
is inserted and HP detection is required, thus saving power at all
other times.
