Since commit 1e2a7d78499e ("irqdomain: Don't set type when mapping
an IRQ"), the interrupt type is strictly checked. Without this
patch, this board would not boot any more.
Documentation/devicetree/bindings/interrupt-controller/arm,gic-v3.txt
says that the 3rd cell should be either 1 (edge) or 4 (level)
depending on the trigger type. As the CA72 Generic Timer provides
active-low interrupts, the value of the 3rd cell should be 4.

Arnd, Olof,
I guess you are about to send pull-reqs for v4.8 cycle.
Could you include this one in them?
After IRQ updates for 4.8 were merged, my board would not
boot at all. I consulted experts and looks like my DT
was wrong.
I could do this after -rc1 is out because it is apparently a
bug fix, but in that case the for-next branch in ASOC will be
broken for me, which would make bisect-ability difficult for me.
