ASoC: soc-cache: Ensure flat compression uses a copy of the defaults cache

Browse Source 
With the addition of the cache fallback functionality, it is necessary
to ensure that if the register defaults cache was marked as __devinitconst
and the LZO compression is not compiled in the kernel, the fallback to
flat compression will still use a copy of the defaults cache.
