ASoC: SDCA: Add completion for FDL start and stop

Browse source

Add some completions and a helper function to allow other parts of the
system to wait for FDL to complete. The sdca_fdl_sync() function will
wait until it completes a full time out without a new FDL request
happening, this ensures that even parts requiring multiple rounds of FDL
should be fully downloaded before the driver boot continues.
