mmc: Add read-only directory to support mboxd

The mboxd implementation assumes that there is a read-only and
read-write directory. During a write request, mboxd copies the
contents of the read-only to the read-write directory. To continue
to support mboxd, mount a read-only directory of the hostfw image
for mboxd to use. Otherwise the write command fails (can't copy
the file to itself) and mboxd exits.

Tested: Verified mboxd didn't fail and system powered on.
