[PATCH] pinctrl: nomadik: don't default-flag IRQs as falling

[Linus Walleij]

There is no point in adding any default trigger for these
GPIO interrupts: the device tree should contain all trigger
information and the platforms using the driver boots
exclusively from device tree.

Also the boot log is nagging me to fix this:

[    0.771057] ------------[ cut here ]------------

   ../drivers/gpio/gpiolib.c:1622 _gpiochip_irqchip_add+0x138/0x160

(...)
[    0.942962] gpio 8012e000.gpio: at address e08f8000
(etc ad nauseam)
