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")
