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"

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

This fixes this warning, but instead creates a new one, because the
reg-names order is fixed in the DT binding:

   reg:
     minItems: 1
     items:
       - description: The function configuration registers base
       - description: The link table configuration registers base
       - description: The cache configuration registers base
  
   reg-names:
     items:
       - const: function
       - const: link
       - const: cache

Oh, right, missed to check the binding.. :-(

See also the prior discussion wrt this:
https://lore.kernel.org/linux-rockchip/edabca63-594e-44ae-8a3d-0f60987a8664@collabora.com/ (local)

That's interesting, I'm also not able to trigger the warning on RK3588.

Regardless, the binding can be easily adjusted with the patch below.  Hence I'm
going to handle this in v2, unless there's a reason against moving further.

Thanks,
Cristian
