The only constraint that has been keeping this driver as bool is that
some machines like, Asus T100, uses ACPI GPIO operation regions for
toggling GPIOs to get things like sensor hub powered on. The GPIO
operation region code does not yet handle -EPROBE_DEFER so only way to
ensure that the operation region is there is to have the driver compiled
in to the kernel.
