[PATCH 1/3] drm: Don't reserve minors for control nodes

[Michał Winiarski]

Control nodes are no longer with us.
While we still need to preserve render nodes numbering, there's no need
to reserve the range formerly used for control. Let's repurpose it to be
used by primary and remove control remains from the code entirely.

References: commit 0d49f303e8a7 ("drm: remove all control node code")
References: commit c9ac371d4b59 ("drm: Fix render node numbering regression from control node removal.")
