[RFC PATCH v5 v5 2/8] dt-bindings: power: rockchip: allow resets in a power domain node

Some domains do not come up in a usable state on their own and need
their resets cycled once power is on. The RK3576 NPU domains are one
case: without it the first access after power-on takes an async SError.

pd-node has no resets property and every nesting level is
unevaluatedProperties: false, so describing that in DT is rejected
today. Add it alongside clocks.
