gpio: mxs: need to check return value of irq_alloc_generic_chip

Browse source

Need to check return value of irq_alloc_generic_chip, because
it may return NULL.
1. Change mxs_gpio_init_gc return type from void to int.
2. Add a new lable out_irqdomain_remove to remove the irq domain
   when mxc_gpio_init_gc fail.
