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) Note that there are a couple places in selftest_mocs.c where the gen9 version of LNCFCMOCS is still used without regards for which platform we're on. Those cases are just doing an offset lookup and not issuing any CPU reads/writes of the register, so the potentially multicast nature of the register doesn't come into play. v2: - Add commit message note about the unconditional GEN9_LNCFCMOCS usage in selftest_mocs. (Bala) - Include some additional TLB registers.
