ASoC: wm_adsp: Implement support for coefficeint file format 1

Browse Source 
Implement support for a new revision of the coefficeint file format for
ADSP cores.

Since coefficient file format 0 has not been widely deployed and is very
unlikely to ever be used with this driver code support for it has been
removed.
