drm/exynos: hdmi: convert to struct drm_edid

Browse Source 
Prefer the struct drm_edid based functions for reading the EDID and
updating the connector.

The functional change is that the CEC physical address gets invalidated
when the EDID could not be read.

v2:
- display info usage was split to a separate patch
- check drm_edid_connector_update() return value
