ASoC: ux500: ux500_msp_i2s: Remove unused variables 'reg_val_DR' and 'reg_val_TSTDR'

Browse source 
Looks like these have been unchecked since the driver's inception in 2012.

Fixes the following W=1 kernel build warning(s):

sound/soc/ux500/ux500_msp_i2s.c: In function ‘flush_fifo_rx’:
sound/soc/ux500/ux500_msp_i2s.c:398:6: warning: variable ‘reg_val_DR’
set but not used [-Wunused-but-set-variable]
sound/soc/ux500/ux500_msp_i2s.c: In function ‘flush_fifo_tx’:
sound/soc/ux500/ux500_msp_i2s.c:415:6: warning: variable
‘reg_val_TSTDR’ set but not used [-Wunused-but-set-variable]
