Consolidate down to just a single 'fwtable' implementation. For reads
we don't need to worry about shadow tables. Also, the
NEEDS_FORCE_WAKE() check we previously had in the fwtable implementation
can be dropped --- if a register is outside that range on one of the old
platforms, then it won't belong to any forcewake range and 0 will be
returned anyway.
