Module Makefile build rules for ofw_bus_if.h are a bit of a mess; some
modules build it unconditionally while others build it only on certain
archs. There are a large number of different combinations of sparc64,
mips, powerpc, arm, and aarch64. This is true for a number of other
arch-specific module Makefile support. Should we have MK_* knobs to
control these cases -- e.g. MK_OFW (MK_FDT?) here? That would at least
move the arch-specific tests to a common location.
