ASoC: ti: Add custom machine driver for j721e Common Processor Board

The audio support on the board is using pcm3168a codec connected to McASP10
serializers in parallel setup.
The pcm3168a SCKI clock is coming via the j721e AUDIO_REFCLK2 pin.
In order to support 48KHz and 44.1KHz family of sampling rates the parent clock
for AUDIO_REFCLK2 needs to be changed between PLL4 (for 48KHz) and PLL15 (for
44.1KHz). The same PLLs are used for McASP10's AUXCLK clock via different
HSDIVIDER.

Generic card can not be used for the board as we need to switch between
clock paths for different sampling rate families and also need to change
the slot_width between 16 and 24 bit audio.
