Add a new pldm feature option

The openpower-process-host-firmware and openpower-update-bios-attr-table
set up the system to use the PLDM protocol instead of hiomap (mboxd).
Since tacoma uses emmc but does not support the host PLDM protocol, need
to make it an optional feature.
Create an optional pldm feature so that the p10bmc systems can opt-in to
it. Once all the PLDM support is in place in the host side, the mboxd
support can be removed from systems that enable this new pldm option.

Tested: Enabled this new pldm feature in p10bmc, verified tacoma and
p10bmc reached power on.
