Runtime scom support for OCMBs
fapi2::getScom on OCMB targets eventually resolves
to a mmio call at runtime.
This commit registers a runtime version of mmioScomPerformOp
to the IBSCOM device ops for OCMB targets.
During runtime, hostboot will rely on the hypervisor (opal/phyp)
to issue the inband commands to perform the operation on the
desired OCMB.
