Subject: pinctrl: at91: use locked variant of irq_set_handler

From: Nicolas Ferre <nicolas.ferre@xxxxxxxxx>

commit b0dcfd87323ea86501e93d0fa2a98d2fd3579bcf upstream.

When setting the gpio irq type, use the __irq_set_handler_locked()
variant instead of the irq_set_handler() to prevent false
spinlock recursion warning.
