Now that the reference to the shadow table is stored within the uncore, we don't need to generate separate fwtable, gen11_fwtable, and gen12_fwtable variants of the register write functions; a single 'fwtable' implementation will work for all of those platforms now.
Note that while consolidating down to __fwtable_reg_write_fw_domains() we drop the NEEDS_FORCE_WAKE() check. If an MMIO offset is outside that range on older platforms, it also won't be part of a range in the forcewake table, so a '0' will be returned anyway.
