ENGR00313685-2 of/irq: Replace of_irq with of_phandle_args

commit 530210c7814e83564c7ca7bca8192515042c0b63 upstream.

struct of_irq and struct of_phandle_args are exactly the same structure.
This patch makes the kernel use of_phandle_args everywhere. This in
itself isn't a big deal, but it makes some follow-on patches simpler.
