drm/i915: Reserve ioctl numbers for set/get_caching
I'm planing to merge this next week for 3.7, but I'd like to avoid stupid conflicts with the exsting userspace when merging the new reg_read ioctl (which doesn't have userspace yet, but this caching interface has). Header extracted from Chris Wilson's patch, but fix up the copy&pasted comment in the interface struct.
