[PATCH v3 0/3] arm64: dts: rockchip: Fix vdec register blocks order on RK3576/RK3588

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"

The first patch updates 'reg-names' property in rockchip,vdec binding to
allow providing the register blocks following the address-based order
and, consequently, ensure the unit address points to the first register
range.

The next two patches reorder 'reg' and 'reg-names' for the impacted
RK3576 & RK3588 video decoder nodes.
