dt-bindings: power: reset: qcom,pon: Narrow allowed reboot modes

Browse Source 
reboot-mode schema allows arbitrary "mode-.* properties but only a
subset actually makes sense and is valid.  Provide negative look-ahead
pattern to disallow any modes not supported by the device, which
tightens the binding.
