ecore-drm: Implement edid parsing for Ecore_Drm_Output

Summary: This implements edid parsing to obtain output make and model
so we can get better output names. This also fixes a false FIXME
statement in ecore_drm_output_physical_size_get function. As it turns
out, we don't need to get these values from edid parsing as they are
already available in the drm connector.
