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.
