I think I'm going to just end up restricting this driver to X86
as was originally suggested.

There seems to be no real consistent Kconfig protection for users
of isa_virt_to_bus() and friends.

We know that ISA_DMA_API doesn't do it, and ISA doesn't do it either
as powerpc also allows that to bet set for CHRP and friends.
