[audio][aml-g12-pdm] Reduce ring buffer size

This is pretty much the same as http://fxrev.dev/449830 but for
PDM input.

Instead of precalculating the ring buffer size according to the
maximum possible parameters to get 1 second of audio, calculate
the size based on the required format and the min_frames parameter.
