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. :-)

and populate it with the common parts from PowerPC and Sparc[64].

This moves all the common parts for the Sparc, Sparc64 and PowerPC
of_device.c files into drivers/of/device.c.
Apart from the simple move, Sparc gains of_match_node() and a call to
of_node_put in of_release_dev(). PowerPC gains better recovery if
device_create_file() fails in of_device_register().

This creates drivers/of/base.c (depending on CONFIG_OF) and puts
the first trivially common bits from the prom.c files into it.
