21451155d8 [POWERPC] of/gpio: Use dynamic base allocation
Since the "gpiolib: dynamic gpio number allocation" patch was recently
merged into Linus' tree (commit 8d0aab2f16),
we can use dynamic GPIO base allocation now.

This, in turn, removes number of gpios per chip constraint.

863fbf4966 [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:

"16-bit I/O port" sounds promising. :-)
