[Intel-gfx] [PATCH] intel: Update for new i915_drm.h defines.

This syncs the code up to the kernel as of the gen7 SOL changes.  It
would be nice if doing this was just a straight copy of the kernel
code -- there are two diffs left out.  One is this hunk:

-#ifdef __KERNEL__
-/* For use by IPS driver */
-extern unsigned long i915_read_mch_val(void);
-extern bool i915_gpu_raise(void);
-extern bool i915_gpu_lower(void);
-extern bool i915_gpu_busy(void);
-extern bool i915_gpu_turbo_disable(void);
-#endif

Does anyone see any real reason to be dropping this?

The other is removing the sparse __user annotations on the structs.
Could we just patch the kernel to #define it away for userland, so we
could make updating this file just a matter of "cp"?
