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.
