ASoC: fsl_sai: replace regmap_write with regmap_update_bits
[ Upstream commit 0e270f32975fd21874185ba53653630dd40bf560 ]
Use the regmap_write() for software reset in fsl_sai_config_disable would
cause the FSL_SAI_CSR_BCE bit to be cleared. Refer to
commit 197c53c8ecb34 ("ASoC: fsl_sai: Don't disable bitclock for i.MX8MP")
FSL_SAI_CSR_BCE should not be cleared. So need to use regmap_update_bits()
instead of regmap_write() for these bit operations.
Fixes: dc78f7e59169d ("ASoC: fsl_sai: Force a software reset when starting in consumer mode")
