ASoC: da7213: add default clock handling

This adds default clock/PLL configuration to the driver
for usage with generic drivers like simple-card for usage
with a fixed rate clock.

ASoC: da7213: Add regulator support

This adds support for most regulators of da7212 for improved
power management. The only thing skipped was the speaker supply,
which has some undocumented dependencies. It's supposed to be
either always-enabled or always-disabled.

ASoC: da7213: fix DAI_CLK_EN register bit overwrite

If the da7213 codec is configured as Master with the DAPM power down
delay time set, 'snd_soc_component_write' function overwrites the
DAI_CLK_EN bit of DAI_CLK_MODE register which leads to audio play
only once until it re-initialize after codec power up.

ASoC: da7213: add support for DSP modes

DSP modes are documented in the data sheet but not enabled in the driver.
The work-around already implemented for DA7218/9 is also required to
make sure the bit clock handling in DSP modes follows ASoC conventions.

ASoC: da7213: Refactor sysclk(), pll() functions to improve handling

Currently the handling of the PLL in the driver is a little clunky,
and not ideal for all modes. This patch updates the code to make it
cleaner and more sensible for the various PLL states.

Key items of note are:
- MCLK squaring is now handled directly as part of the sysclk()
function, removing the need for a private flag to set this feature.
- All PLL modes are defined as an enum, and are handled as a case
statement in pll() function to clean up configuration. This also
removes any need for a private flag for SRM.
- For 32KHz mode, checks are made on codec master mode and correct
MCLK rates, to avoid incorrect usage of PLL for this operation.
- For 32KHz mode, SRM flag now correctly enabled and fout set to
sensible value to achieve appropriate PLL dividers.

ASoC: da7213: Default PC counter to free-running when DAI disabled

Currently PC counter is always synchronised to DAI which means that
when the DAI is disabled, features such as ALC calibration cannot
be executed successfully. This patch makes sure that when the DAI
is disabled, PC counter is set to free-running.

ASoC: da7213: Add checking of SRM lock status before enabling DAI

When the codec is DAI clk slave, and the SRM feature of the PLL
is being used, the enabling of the DAI should occur only after
the PLL has locked to the incoming WCLK. This update adds checking
to the the DAI widget event, so it waits for SRM to lock. There is
also a timeout if that lock doesn't occur within a given time.

ASoC: da7213: Add DAI DAPM event to control DAI clocks

Currently, when Codec is I2S master DAI clocks are continuously
generated even if all audio streams have stopped. To improve
efficiency, control of the DAI clocks for master mode have been
moved to a DAPM widget event so they're only enabled as required.

ASoC: da7213: Add support to handle mclk data provided to driver

Driver now can make use of mclk data, if provided, to set, enable

enable clock squaring is dealt with as part of dai_sysclk() call
rather than as platform data.
