ASoC: SOF: ipc4: Handle compressed drain done notification from firmware

Browse Source 
The decoder module sends a drain done notification when the last chunk of
the stream after the EOS from host has been decoded.

The notification is a module notification with 0xc0c0 as magic number in
event_id upper 16 bit.

Call sof_ipc4_compr_drain_done() when the notification arrives to handle
it.
