drm/edid: add HF-EEODB support to EDID read and allocation
HDMI 2.1 section 10.3.6 defines an HDMI Forum EDID Extension Override
Data Block, which may contain a different extension count than the base
block claims. Add support for reading more EDID data if available. The
extra blocks aren't parsed yet, though.
Hard-coding the EEODB parsing instead of using the iterators we have is
a bit of a bummer, but we have to be able to do this on a partially
allocated EDID while reading it.
v2:
- Check for CEA Data Block Collection size (Ville)
- Amend commit message and comment about hard-coded parsing
