ASoC: Intel: avs: Abstract IPC handling

Servicing IPCs on CNL platforms and onward differs from the existing

representing crucial IPC registers and utilize them throughout the code.

While cleaning up device descriptors, reduce the number of code lines by
assigning 'min_fw_version' within a single line.
