[POWERPC] Add of_device_is_available function
IEEE 1275 defined a standard "status" property to indicate the operational
status of a device. The property has four possible values: okay, disabled,
fail, fail-xxx. The absence of this property means the operational status
of the device is unknown or okay.
This adds a function called of_device_is_available that checks the state
of the status property of a device. If the property is absent or set to
either "okay" or "ok", it returns 1. Otherwise it returns 0.
