drm/edid: add new interfaces around struct drm_edid
Add new functions drm_edid_read(), drm_edid_read_ddc(), and drm_edid_read_custom() to replace drm_get_edid() and drm_do_get_edid() for reading the EDID. The transition is expected to happen over a fairly long time. Note that the new drm_edid_read*() functions do not do any of the connector updates anymore. The reading and parsing will be completely separated from each other. Add new functions drm_edid_alloc(), drm_edid_dup(), and drm_edid_free() for allocating and freeing drm_edid containers.
