diffstat removes more than it adds, and it only adds when there are funcs
which need to be customized in the first place, I think this holds to the
desire to ultimately kill off (when possible) the misc sub gpio headers.
After all, if you can kill the overridden function, my additional lines
shouldn't be needed either.
I don't have any toolchains for avr32, microblaze, openrisc, unicore32,
or xtensa. So they lose :x.

v2
- grub through arm gpio.h headers
- add m68k support
note: i've done a full build of all arm defconfigs, and any warnings
or build failures appear to be unrelated to my change (sadly, there
seem to be way more than there should be ...). i'll start a 2nd
build which compares the binary output to make sure they're the
same, but if people see something that needs more attention before
that, feel free to highlight it.
