ARM: dts: Fix omap serial wake-up when booted with device tree
We've had deeper idle states working on omaps for few years now, but only in the legacy mode. When booted with device tree, the wake-up events did not have a chance to work until commit 3e6cee1786a1 (pinctrl: single: Add support for wake-up interrupts) that recently got merged. In addition to that we also needed commit 79d9701559a9 (of/irq: create interrupts-extended property) and 9ec36cafe43b (of/irq: do irq resolution in platform_get_irq) that are now also merged. So let's fix the wake-up events for some selected omaps so devices booted in device tree mode won't just hang if deeper power states are enabled, and so systems can wake up from suspend to the serial port event. Note that there's no longer need to specify the wake-up bit in the pinctrl settings, the request_irq on the wake-up pin takes care of that.
