Subject: [PATCH] ARM: tegra: dalmore: fix irq trigger type

Trigger type needs to be IRQ_TYPE_LEVEL_HIGH since the interrupt
signal gets inverted by the PMC (configured by the invert-interrupt
property).

I could not test that patch since I don't have such hardware.
However, I stumbled on that error while tracing a similar error
on Colibri T30.
