[FEATURE] check-alsabat support multiple frequencies test

[fredoh9]

This is not a problem but for enhancement.

Instead of testing one frequency at a time, can we give array of frequency? like 599, 821, 9927 etc.
Covering different frequencies is good idea but it generates too many test case entries, 3 for playback, 3 for capture and 3 32bit for nocodec.
