ASoC: SOF: Copy compress parameters into extended data

Browse source 
Allocate memory at the end of sof_ipc_stream_params to store
snd_compr_params in order to be sent them to SOF firmware.

This will help firmware correctly configure codecs parameters.

Notice, that we use 2 bytes from the reserved pool in order to store
the extended data length. This is compatible with older FWs where
there was no extended data.
