drm-misc-next for 4.17:

UAPI Changes:
- Validate mode flags + type (Ville)
- Deprecate unused mode flags PIXMUX, BCAST (Ville)
- Deprecate unused mode types BUILTIN, CRTC_C, CLOCK_C, DEFAULT (Ville)

Cross-subsystem Changes:
- MAINTAINERS: s/Daniel/Maarten/ for drm-misc (Daniel)

Core Changes:
- gem: Export gem functions for drivers to use (Samuel)
