[PATCH 4/9] gpio: mxc: use devm action for irq_domain cleanup

[Peng Fan (OSS)]

From: Peng Fan <peng.fan at nxp.com>

Replace the manual irq_domain_remove() error path with
devm_add_action_or_reset(), so the IRQ domain is cleaned up
automatically on both probe failure to eliminate the
out_irqdomain_remove goto label.
