arm64: select ARCH_WANT_OPTIONAL_GPIOLIB 

An architecture should not unconditionally enable 'GENERIC_GPIO'
without providing an implementation. In case of arm64, selecting
ARCH_WANT_OPTIONAL_GPIOLIB is the right solution, because it
lets us enable GPIOLIB when configuring the kernel, and that
implicitly turns on GENERIC_GPIO.
