via changes: 

1. Initialize futex locks to zero on device init.
2. Remove some stray defines from via_drm.h
3. Prepare via_drm.h for drm client inclusion. The goal is to share a
    common file with common definitions.
4. Sync shared / shared-core via_drm.h
5. Bump minor, because of the futex lock initialization.
