Not a big deal, but I'm happy if we can use same naming rule
for same things.

	rtd->dai_link->symmetric_samplebits;
	                         ^^^^^^^^^^
	dai->driver->symmetric_samplebits;
	                       ^^^^^^^^^^
	cpu_dai->sample_bits
	         ^^^^^^^^^^^

	__soc_pcm_params_symmetry(rate,		rates);
	                          ^^^^^         ^^^^^
	__soc_pcm_params_symmetry(sample_bits,	samplebits);
	                          ^^^^^^^^^^^   ^^^^^^^^^^

Thank you for your help !!
