drm/edid: use struct drm_edid for override/firmware EDID
There's a lot going on here, but the main thing is switching the
firmware EDID loader to use struct drm_edid. Unfortunately, it's
difficult to reasonably split to smaller pieces.
Convert the EDID loader to struct drm_edid. There's a functional change
in validation; it no longer tries to fix errors or filter invalid
blocks. It's stricter in this sense. Hopefully this will not be an
issue.
As a by-product, this change also allows HF-EEODB extended EDIDs to be
passed via override/firmware EDID.
