So I'm annoying, but I think this is a really good time to standardize all
these and push them into drm_connector_state. With docs and everything.
They are already core properties, might as well properly decode them if
they're present.

I can help with typing the kernel-doc for this stuff, right now the DOC:
section in drm_connector.c only documents the standard props, none of the
ones you can add by calling one of the helpers.

Sorry I'm this late with this feedback, but I feel fairly strongly about
decoding standardized props in the core and putting them into shared
structs.
