of: Rename "poweroff-source" property to "system-power-controller"
It reverts commit a4b4e0461ec5 ("of: Add standard property for poweroff capability"). As discussed on the mailing list, it makes more sense to rename back to the old established property name, without the vendor prefix. Problem being that the word "source" usually tends to be used for inputs and that is out of control of the OS. The poweroff capability is an output which simply turns the system-power off. Also, this property might be used by drivers which power-off the system and power back on subsequent RTC alarms. This seems to suggest to remove "poweroff" from the property name and to choose "system-power-controller" as the more generic name. This patchs adds the required renaming changes and defines an helper function which checks if this property is set.
