When building device trees for the RK3576 based boards, DTC shows the
following complaint:

  rk3576.dtsi:1282.30-1304.5: Warning (simple_bus_reg): /soc/video-codec at 27b00000: simple-bus unit address format error, expected "27b00100"

Provide the register blocks in the expected address-based order.

Fixes: da0de806d8b4 ("arm64: dts: rockchip: Add the vdpu383 Video Decoder on rk3576")
