drm/i915: Implement GPU semaphores for inter-ring synchronisation on SNB
The bulk of the change is to convert the growing list of rings into an array so that the relationship between the rings and the semaphore sync registers can be easily computed. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
