MLK-14847: Revert "ASoC: fsl-sai: set xCR4/xCR5/xMR for SAI master mode"

This reverts commit c768ed336bba ("ASoC: fsl-sai: set xCR4/xCR5/xMR for
SAI master mode")

This change was already introduced by commit 51659ca069ce ("ASoC: fsl-sai:
set xCR4/xCR5/xMR for SAI master mode") from upstream.

Manually adjust the code to match the changes introduced by subsequent
commit b2936555bb38 ("MLK-13609: ASoC: fsl_sai: fix for synchronize mode")
by removing updates to FSL_SAI_TMR/FSL_SAI_RMR registers.
