drm/sti/sti_hdmi: convert to struct drm_edid

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: Use drm_edid_read() instead of drm_edid_read_ddc() (Sima)
