Subject: [PATCH] ARM: dts: Enable UART wake-up events for beagleboard
For device tree based booting, we need to use wake-up
interrupts like we already do for some omaps. This fixes
a PM regression on beagleboard compared to legacy booting.

The above patch works for me with ret/off-idle on beagle rev C4 on top
of 3.16-rc5. Without it, the board just seems to hang with ret, and with
off, it just doesn't respond to anything on uart but seems alive otherwise.
