cd8fff504d drm/sun4i: Add a DRC driver
The A33 pipeline also has a component called DRC. Even though its exact
features and programming model is not known (or documented), it needs to
be clocked for the pipeline to carry the video signal all the way.

Add a minimal driver for it that just claim the needed resources for the
pipeline to operate properly.

440d2c7b12 drm/sun4i: backend: Handle the SAT
The A33 has an block called SAT that is part of the backend that needs to
be clocked and out of reset to be able for the backend to operate properly.

Extend the binding to have the SAT resources listed, and claim them when
the backend probes.

The A33 has a significantly different pipeline, with components that differ
too.

Make sure we had compatible for them.
