drm: Remove references to removed transitional helpers

Browse Source 
The transitional helpers were removed a long time ago, but some
references stuck.  Remove them.

* This helper library contains helpers to implement primary plane support on

* planes, and newly merged drivers must not rely upon these transitional
* helpers.
*
* The second part also implements transitional helpers which allow drivers to
* gradually switch to the atomic helper infrastructure for plane updates. Once
* that switch is complete drivers shouldn't use these any longer, instead using
* the proper legacy implementations for update and disable plane hooks provided
* by the atomic helpers.
*
* Again drivers are strongly urged to switch to the new interfaces.
*
* The plane helpers share the function table structures with other helpers,
* specifically also the atomic helpers. See &struct drm_plane_helper_funcs for
* the details.
