Timur Kristóf 494941aa77 drm/amd/display: Allow embedded connectors without DDC 
On some laptops, the embedded panel may not have
a DDC (display data channel) available. On these,
the EDID may be hardcoded in ACPI or the VBIOS.

In this case, use GPIO_DDC_LINE_UNKNOWN and don't fail.

Fixes: def3488eb0 ("drm/amd/display: refactor HPD to increase flexibility")
