mmc: Support a patch directory for each version

Create a patch directory for the running and alternate hostfw
versions. Otherwise the patches may not be compatible if a
side switch occurs.

Also don't delete patches when updating the running version
because it's not known if it's just a side switch. This should
be handled by the code update app which currently is done by
the BMC updater.
