drm/i915/: Re-work clflush_write32

Browse source

Use drm_clflush_virt_range instead of clflushopt and remove the memory
barrier, since drm_clflush_virt_range takes care of that.

v2(Michael Cheng): Use sizeof(*addr) instead of sizeof(addr) to get the
		   actual size of the page. Thanks to Matt Roper for
		   pointing this out.
