Fix lpaif_type and DAI configuration for I2S
Merge series from Mohammad Rafi Shaik <mohammad.rafi.shaik@oss.qualcomm.com>:
Fix the lpaif_type configuration for the I2S interface.
The proper lpaif interface type required to allow DSP to vote
appropriate clock setting for I2S interface and also Add support
for configuring the DAI format on MI2S interfaces to allow setting
the appropriate bit clock and frame clock polarity, ensuring correct
audio data transmissionover MI2S.
