gpiolib: remove warnning of allocations with IRQs disabled
Move of_gpiochip_add outof spin_lock, since kzalloc inside
of_gpiochip_add -> of_gpiochip_add_pin_range -> gpiochip_add_pin_range -> kzalloc
WARNING: at kernel/lockdep.c:2740 lockdep_trace_alloc+0xf8/0xfc()
DEBUG_LOCKS_WARN_ON(irqs_disabled_flags(flags))
