[PATCH] intel: Update i915_drm.h and correct misspelled caching

[Sedat Dilek]

AFAICS, there are more updates needed to be in sync with recent kernel-drm.

I fell over the misspelling when digging into an issue in Linux-next.
The spelling should be consistent in kernel-drm, libdrm, intel-ddx, etc.
Here, I had a look especially at the defined macros (defines).
