[PATCH 4/5] drm/rockchip: lvds: Fix component unbind

[Ezequiel Garcia]

Remove the explicit encoder disable: it's
already part of the CRTC shutdown, in both
atomic and legacy API cases.

Also, encoder and connector cleanup is performed
by the DRM .destroy hooks, for encoder and connector
respectively. It can be removed as well.

Finally, move the panel detach call to the connector
.destroy hook, where it belongs.
