dt-bindings: rockchip: pmu: Narrow definition of reboot-mode

Browse source

The 'reboot-mode' child of PMU node must be a syscon-reboot-mode one, so
add missing $ref to enforce the validation and disallow other
reboot-mode handlers.
Defining 'type: object' is on the other hand not necessary when other
schema is referenced.

This can be further restricted to match hardware/firmware:
syscon-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.
