avr32: Fix GPIO initcall breakage
Add essential system devices, including GPIO controllers, automatically
at core_initcall time. This ensures that the devices are there when the
PIO driver gets initialized at postcore_initcall, fixing a bug exposed
by commit d6634db8fe1784d0a8e4e156970fec034708446e "avr32: Use
platform_driver_probe for pio platform driver".
