gpio: qpnp-pin: reorder qpnp-pin device register

The qpnp-pin device register needs to take place
earlier than device_initcall because qpnp-pin device
could be used in other devices which are registered in
device_initcall. This patch reorder device register
by using arch_initcall instead of module_init
