ARM: remove include of mach/gpio.h for gpiolib users

gpiolib user have nothing to define in their machine
specific gpio.h, so do not include it.

The only thing they could define would be ARCH_NR_GPIOS,
but currently no architecture defines it. Should an architecure
feel the need to do it this would be a good opportunity to
get rid of this limitation.
