cbfs: Skip mcache in post-RAM stages before CBMEM is online
There have been a few issues with the new CBFS mcache code in stages
after romstage, where the mcache resides in CBMEM. In a few special
cases the stage may be doing a CBFS lookup before calling
cbmem_initialize(). To avoid breaking those cases, this patch makes the
CBFS code fall back to a lookup from flash if CBMEM hasn't been
reinitialized yet in those stages.
