ARM: Remove dependency of plat-orion GPIO code on mach directory includes.
This patch makes the various mach dirs that use the plat-orion GPIO
code pass in GPIO-related platform info (GPIO controller base address,
secondary base IRQ number, etc) explicitly, instead of having
plat-orion get those values by including a mach dir include file --
the latter mechanism is problematic if you want to support multiple
ARM platforms in the same kernel image.
