The G1 and G2 are separate decoder blocks that are enabled by the vpu-blk-ctrl power-domain controller, which now has a proper driver. Update the bindings to support separate nodes for the G1 and G2 decoders using the proper driver or the older unified node with the legacy controls. To be compatible with older DT the driver, mark certain items as deprecated and retain the backwards compatible example.
