With the recent pinctrl-single changes, SoCs such as Texas
Instrument's OMAP processors can treat wake-up events from deeper idle
states as interrupts.
Let's add support for the optional second interrupt for wake-up using
the generic wakeirq support added in commit 4990d4fe32 ("PM /
Wakeirq: Add automated device wake IRQ handling")
Finally, to pass the wake-up interrupt in the dts file,
interrupts-extended property needs to be passed.
This is similar in approach to commit 2a0b965cfb ("serial: omap: Add
support for optional wake-up") + ee83bd3b64 ("serial: omap: Switch
wake-up interrupt to generic wakeirq")
