arm64: dts: rockchip: Fix vdec register blocks order on RK3576

Browse Source 
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@27b00000: simple-bus unit address format error, expected "27b00100"

Since the video decoder support for the aforementioned SoC in mainline
driver and devicetrees hasn't been released yet (just landed in
v7.0-rc1), fix the issue by providing the register blocks using the
'link,function,cache' listing, which follows the address-based order as
shown in the vendor's datasheet and, implicitly, ensures the unit
address points to the primary register range.
