Starting in Xe_HP, several registers our driver works with have been
converted from singleton registers into replicated registers with
multicast behavior. Although the registers are still located at the
same MMIO offsets as on previous platforms, let's duplicate the register
definitions in preparation for upcoming patches that will handle
multicast registers in a special manner.
The registers that are now replicated on Xe_HP are:
* PAT_INDEX (mslice replication)
* FF_MODE2 (gslice replication)
* COMMON_SLICE_CHICKEN3 (gslice replication)
* SLICE_COMMON_ECO_CHICKEN1 (gslice replication)
* SLICE_UNIT_LEVEL_CLKGATE (gslice replication)
* LNCFCMOCS (lncf replication)
Bspec: 66534
