media: rkvdec: Add H264 support for the VDPU383 variant

This variant is used on the RK3576 SoC.

The moving vectors size requirements are slightly different so support
for a colmv_size function per variant is added.

Also, the link registers are used to start the decoder and read IRQ status.

The fluster score is 128/135 for JVT-AVC_V1, with MPS_MW_A failing in
addition to the usual ones.
The other test suites are not supported yet.
