MIPS: AR7: Defer registration of GPIO
commit e6b03ab63b4d270e0249f96536fde632409dc1dc upstream.
When called from prom init code, ar7_gpio_init() will fail as it will
call gpiochip_add() which relies on a working kmalloc() to alloc
the gpio_desc array and kmalloc is not useable yet at prom init time.
Move ar7_gpio_init() to ar7_register_devices() (a device_initcall)
where kmalloc works.
Fixes: 14e85c0e69d5 ("gpio: remove gpio_descs global array")
