This avoids residual bit form previous format when the format is changed.
Hence, the resultant format is not an invalid one.

TDM related settings for ACP registers in hw_params.
When TDM mode is enabled, Hw_params needs to read and write
from/to respective TX/RX (ACP_(I2S/BT)TDM_(TX/RX)FRMT) registers.

Because of MAX BUFFER size in register,when user/app give small
buffer size produces noise of old data in buffer.
This patch rectifies this noise when using different
buffer sizes less than MAX BUFFER.

Stopping of one stream is killing the other stream when they
are running simultaneously. This is because, IER register is
cleared which disables I2S and overrides any other block enables.
Clearing IER register only when all streams on a channel are disabled,
fixes the issue.

In case of error, the function devm_ioremap() returns NULL pointer not
ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.

This patch adds I2S SP support in ACP PCM DMA and DAI.
Added I2S support in DMA and DAI probe,its hw_params handling
its open and close functionalities.
This enables to open and close on the SP instance for
playback and capture.
