This is currently used on ARM and sandbox, but it's relevant for
other platforms like x86 as well if driver code wants to make use
of the functions defined within.
MIPS and PowerPC already defines the symbols, but that's ok because
<bitio.h> doesn't override existing macros. This works for MIPS, but
not PowerPC, where those aren't macros. Fix that up.
