ASoC: stm32: sai: remove set but not used variables 'mask, cr1'
Fixes gcc '-Wunused-but-set-variable' warning:
sound/soc/stm/stm32_sai_sub.c: In function 'stm32_sai_configure_clock':
sound/soc/stm/stm32_sai_sub.c:902:11: warning:
variable 'mask' set but not used [-Wunused-but-set-variable]
sound/soc/stm/stm32_sai_sub.c:902:6: warning:
variable 'cr1' set but not used [-Wunused-but-set-variable]
It's not used any more after 8307b2afd386 ("ASoC: stm32: sai: set sai as
mclk clock provider")
