ASoC: simple-card-utils: Split simple_fixup_sample_fmt func

Browse Source 
Split the simple_fixup_sample_fmt() into two functions by adding
one more function named simple_util_get_sample_fmt() to return
the sample format value.

This is useful for drivers that wish to simply get the sample format
without setting the mask.
