ARM: 7049/1: mach-sa1100: move SA1100 GPIO driver to GPIO subsystem
As per example from the other ARM boards, push the SA100 GPIO driver down to the GPIO subsystem so it can be consolidated. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
