Subject: [PATCH RESEND 10/10] drm/todo: remove task for idr_init_base()

All IDRs in the DRM core and drivers which are applicable for using
idr_init_base() over idr_init() should be set up to use a proper base in
order to avoid unnecessary tree walks.

-idr_init_base()
----------------
-
-DRM core&drivers uses a lot of idr (integer lookup directories) for mapping
-userspace IDs to internal objects, and in most places ID=0 means NULL and hence
-is never used. Switching to idr_init_base() for these would make the idr more
-efficient.
