[PATCH 6/6] gpio: orion: register at coredevice level

[Michael Grzeschik <grzeschik@puzzle.ch>]

On boards without deep probe, all devices are created at core_initcall
and each driver probes its devices when it registers. The orion GPIO
driver registered at device level, like its consumers, and drivers/led
and drivers/input are linked before drivers/gpio, so gpio-leds and
gpio-keys were always probed before the GPIO controllers existed:

  gpio-leds gpio-leds.of: error Requested probe deferral: getting gpio for /gpio-leds/led-level
  gpio_keys gpio_keys.of: error Requested probe deferral: requesting gpio #0

They succeeded on the deferred retry, but the messages look like errors
with a debug log level. Register at coredevice level like most other GPIO
controller drivers, so the controllers are there before their users.
