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

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:

(etc ad nauseam)
