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. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
