[POWERPC] OF helpers for the GPIO API
This implements various helpers to support OF bindings for the GPIO
LIB API.
Previously this was PowerPC specific, but it seems this code isn't
arch-dependent anyhow, so let's place it into of/.
SPARC will not see this addition yet, real hardware seem to not use
GPIOs at all. But this might change:
