Timur Kristóf 6c2cce5b54 drm/amd/display: Read EDID from VBIOS embedded panel info 
[ Upstream commit 9ea16f6418 ]

Some board manufacturers hardcode the EDID for the embedded
panel in the VBIOS. This EDID should be used when the panel
doesn't have a DDC.

For reference, see the legacy non-DC display code:
amdgpu_atombios_encoder_get_lcd_info()

This is necessary to support embedded connectors without DDC.
