Merge series "ASoC: Intel: Add KeemBay ASoC platform driver" from Sia Jee Heng <jee.heng.sia@intel.com>:

The below series of patches support the KeemBay ASoC platform driver.
The platform driver initialize the i2s to capture and playback the
pcm data on the ARM. The i2s is running in polling mode.

There is no DSP in the KeemBay SoC. Users are rely on the Gstreamer plugin
to perform Audio preprocessing.

Audio graph card is used to connect the platform driver with the
tlv320aic3204 codec.

Change History:
v5:
- Remove OF dependency from Kconfig as OF is shifted to audio graph card.

v4:
- Reduce if-otology at the tx/rx function.
- Fix indentation.
- specify .rate directly

v3:
- Adjusted header format.
- Use Audio graph card instead of custom sound card.
- Use if-else instead of conditional operator.
- Enabled .set_fmt to configure master clock.

v2:
- Corrected I2S naming for DT binding.

v1:
- Initial version.
