drm/mcde: dsi: convert to of_drm_find_and_get_bridge()

of_drm_find_bridge() is deprecated. Move to its replacement
of_drm_find_and_get_bridge() which gets a bridge reference, and ensure it
is put when done.

We need to handle the two cases: when a panel is found and when it isn't,
even though the latter is not supported. So:

 * in case a panel is not found and bridge is, get a reference to the
   found bridge
 * in case a panel is found, get a reference to the panel_bridge when it
   is added, so the following code always get exactly one reference that
   it needs to put

Finally, use the next_bridge pointer in struct drm_bridge in order to
simplify putting the reference.
