[1/4] drm: Fix DRM_MINOR limits for control and render nodes

Commit Message

From: Kristian Høgsberg <[e-mail]>

We got the minor number base right, but limit is too big and causes the
minor numer ranges for the control and render nodes to overlap.

v2: fix a off-by-one overlap as suggested by [e-mail]
