ASoC: da7219: Improve the relability of AAD IRQ process

- Configure the default gound switch delay time before enabling IRQ
to avoid the unexpected delay time is set up
- Apply DA7219 AAD own work queue to handle AAD events
- Replace msleep with queue_delayed_work to have better relability

This commit improves the control of ground switches in AAD IRQ

ASoC: da7219: Improve the IRQ process to increase the stability

Remove the sleep control in IRQ thread
and create an individual task to handel it for Jack plug in event.

This commit improves the control of ground switches in the AAD IRQ.

ASoC: da7219: Fix pole orientation detection on OMTP headsets when playing music

The OMTP pin define headsets can be mis-detected as line out
instead of OMTP, causing obvious issues with audio quality.
This patch is to put increased resistances within
the device at a suitable point.

To solve this issue better, the new mechanism setup
ground switches with conditional delay control
and these allow for more stabile detection process
to operate as intended. This conditional delay control
will not impact the hardware process
but use extra system resource.

This commit improves control of ground switches in the AAD logic.

ASoC: hdac_hdmi/nau8825/rt286/rt298/rt5663/da7219: replace codec to component

Now we can replace Codec to Component. Let's do it.

Because intal/rockchip boards are using multi-codecs in 1 driver,
we need to update these all related drivers in same time.
Otherwise compile error/warning happen

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.

# 6a0b87c6 12-Sep-2016 Adam Thomson <Adam.Thomson.Opensource@diasemi.com>

ASoC: da7219: Support HP detect procedure when MCLK not present

Currently the driver code assumes that MCLK will be present during
the procedure, or if it has control of MCLK then it can make sure
it's enabled. Some platforms however do not provide MCLK to the
driver in this way, and will not leave MCLK enabled when Codec is
in STANDBY state.

This patch adds support for the HP detect procedure when running
from the device's internal oscillator, to ensure all platforms
can make use of this feature correctly.
