Subject: [PATCH 0/8] Prepare for new rkvdec variants

This patch set introduces the necessary bits for new variants
implementations that do not modify the driver.
The driver changes will come in another patch set.

The first 4 patches document the device nodes and then add the nodes for
rk3588 and rk3576. I kept the R-b tag from Conor Dooley as the patch
didn't change much from [1]. I can remove it if needed.

Then a new v4l2 control for HEVC is added to be able to send the missing
RPS information to the driver.

Finally, the driver is unstaged as the TODO points are removed. I added
myself as maintainer for now as I'll be adding support for several
variants.

Those 3 parts can be applied separately and do not depend on each other.
Based on v6.16-rc3.
