This patch series re-work a few i915 functions to use drm_clflush_virt_range
instead of calling clflush or clflushopt directly. This will prevent errors
when building for non-x86 architectures.

v2: s/PAGE_SIZE/sizeof(value) for Re-work intel_write_status_page and added
more patches to convert additional clflush/clflushopt to use drm_clflush*.
(Michael Cheng)

v3: Drop invalidate_csb_entries and directly invoke drm_clflush_virt_ran 

v4: Remove extra memory barriers
