drm/amd/display: Change EDID fallback condition

Browse source

[Why]
Partially valid EDIDs on MST sinks are treated the same way as broken
EDIDs or read failures and result in a fallback EDID being used instead.

[How]
If edid_status is EDID_PARTIAL_VALID, prefer to use the valid EDID
blocks instead of using a fallback EDID.
