arm64: dts: rockchip: Add VPU support for RK3568/RK3566

RK356x has Hantro G1 video decoder capable to decode MPEG2/H.264/VP8
video formats.

This patch enables RK356x video decoder in RK356x device-tree
include.

Tested on [1] with FFmpeg v4l2_request code taken from [2]
with MPEG2, H.642 and VP8 samples with results [3].
