gpio: allow setting ARCH_NR_GPIOS from Kconfig
The ARM version of asm/gpio.h basically just contains the same definitions
as the gpiolib version, with the exception of ARCH_NR_GPIOS.
This adds the option for overriding the constant through Kconfig to
the architecture-independent header, so we can remove the ARM specific
file later.
