[PATCH 3/5] drm/panel: get/put panel reference in drm_panel_add/remove()

[Anusha Srivatsa]

Take the panel reference and put it back as required
using the helpers introduced in previous patch.
drm_panel_add() and drm_panel_remove()
add a panel to the global registry and removes a panel
respectively, use get() and put() helpers to keep up
with refcounting.
