How about reversing the logic to make it

	bool "64 bit Memory and IO resources (EXPERIMENTAL)" if (RESOURCES_64BIT_ENABLE && EXPERIMENTAL)

Then each architecture could either have

config RESOURCES_64BIT_ENABLE
	def_bool y if !64BIT

or even

	select RESOURCES_64BIT

to switch it on unconditionally.
