The macros just called BUG(), but that results in unused variable
warnings all over the place, like in the IPMI driver.  The build
regression emails were annoying me, so here's the fix.  I have
not even compile tested this, but it's rather obvious.

Too many drivers fail at IOPORT vs IOMEM checking before blindly calling
in to the API, so we may as well just provide basic stubs to get more
build coverage. Other platforms already do this, too (tile, parisc, etc.)
