mmc: Set clear NVRAM bios attribute during factory reset

During factory reset, instead of calling the PLDM services to delete the
PHYP NVRAM files, set the pvm_clear_nvram bios attribute to Enabled to
signal the hypervisor to clear NVRAM when it starts up.

Add the nvram hostfw directory to the list of directories to preserve
during a factory reset because the NVRAM files would now be cleared by
the hypervisor after reading the bios attribute.

Tested: Verified the pvm_clar_nvram bios attribute was set to Enabled as
part of factory reset. Verified a journal error message was logged if
the attribute did not exist and the rest of the factory reset actions
were executed.
