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.
