oem_ibm: Move the NVRAM files to the hostfw directory
This commit would :
- Move the NVRAM files from /var/ on the BMC to the hostfw directory so
that they don't get erased during a BMC factory reset.
- To help migrate existing systems, check if the files exist in /var/,
and if they do, move them to the hostfw destination.
- This also adds dependent services that ensure that the links being
setup correctly in var/lib/phosphor-software-manager/hostfw/ is run
first.
- The services to clear PHYP NVRAM are not needed anymore. Instead of
the BMC clearing them, the hypervisor will now clear them if the
pvm_clear_nvram bios attribute is set.
