drm/i915/gem: Make caps.scheduler static

소스 검색 
We do not notify userspace when the scheduler capabilities are changed
(due to wedging the driver) and as such userspace will expect the caps
to be static and unchanging. Make it so, and so we only need to compute
our caps once during driver registration.
