snd_soc_params_to_bclk() calculates the BCLK from only the information in
snd_pcm_hw_params. It is therefore a subset of the functionality of
snd_soc_tdm_params_to_bclk() so can use a subset of the test case table.

Create a new kunit test for soc-utils and use it to test
snd_soc_tdm_params_to_bclk().
The test uses a table of values to avoid the possibility that an
on-the-fly generator contains the same algorithmic error as the
function-under-test and so fails to detect a bug.
There is no need to test every possible combination of values.
Enough test cases are included to give confidence that the function
is producing the correct results.
