Remove accidental (?) EDID modification while parsing, and constify EDID in most places during EDID parsing.
In the future I'll want more clarity on who modifies the EDID and where, and I'll want the compiler to help.
The EDID is still mutable in places that do validity checking and try to fix it in the process. I'll probably want to split the two into separate check and fix steps too, but that's for another series.
This is based on current drm-tip, without the CEA iterators work.
BR, Jani.
