[PATCH 1/3] drm: change DROP_MASTER permissions to allow DRM_MASTER

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

Currently only DRM_ROOT_ONLY is allowed to call the ioctl.

Change that to DRM_MASTER, which means that only a process that is the
current DRM master can drop it. Which makes sense, the process should
be able to opt-out without any specific requirements.
