pinctrl: at91: Use generic irq_{request,release}_resources()
The at91-specific irq_{request,release}_resources() callbacks are
identical to the generic ones, modulo the bug fix in 5b76e79c77264899
("gpiolib: irqchip: prevent driver unloading if gpio is used as irq
only").
Until commit 8b67a1f0ad1f260f ("gpio: don't override irq_*_resources()
callbacks"), the buggy at91-specific callbacks were never used, though.
Hence drop the at91-specific ones in favor of the generic ones.
