[PATCH v2 10/10] ASoC: fsl_sai: Don't write CHMOD to the other direction's xCR4

[phucduc . bui]

From: bui duc phuc <phucduc....@gmail.com>

When the current direction is synced to the other one, hw_params()
also writes the frame configuration to the other direction's xCR4.
The mask includes CHMOD, whose value is set by the current direction
(Tx only) but written to the other one, so it is wrong:
- TCR4[CHMOD] is cleared, while Tx needs it set (output mode).
- RCR4 bit 5 is set, while it is reserved and must be written as 0.

CHMOD is not part of the frame configuration, so drop it from the mask.

Fixes: f4c4b1bb2f5a ("ASoC: fsl_sai: Set SAI Channel Mode to Output Mode")
