ASoC: zx296702-i2s: remove unused ‘format’

Browse source 
In zx_i2s_hw_params(), 'format' is initialized and assigned bits based on
params_format, but never used. So remove it.

sound/soc/zte/zx296702-i2s.c: In function ‘zx_i2s_hw_params’:
sound/soc/zte/zx296702-i2s.c:228:21: warning: variable ‘format’ set but not used [-Wunused-but-set-variable]
  unsigned long val, format;
