mmc: Add nvram hostfw directory

Created an nvram directory to store the hypervisor's NVRAM files.
Create a symlink to that directory for apps like PLDM to access it.
Add a dependency to the symlink service to start before the PLDM
services that would make use of the new NVRAM directory start.

Tested: Verified the directory and symlink got created. Verified the
PLDM services started after the symlink one.
