Add the out-band-wakeup property for nodes that are out-of-band wakeup capable. Out-of-band wakeup is when a device is in a power domain that is OFF, but the device is still is able to wakeup the system. This will allow drivers to set the out_band_wakeup flag if the out-band-wakeup property is present.

Duplicating my comment from LKML (although I expect discussion to continue there, not here):
This sounds like something you should be able to determine from
device specific compatibles for these platforms. Not sure why they are
not used for this particular device, but this is an indication to me
that that is a mistake.
