drm/i915/gt: Re-work reset_csb

Browse source

Use drm_clflush_virt_range instead of directly invoking clflush. This
will prevent compiler errors when building for non-x86 architectures.

v2(Michael Cheng): Remove extra clflush

v3(Michael Cheng): Remove memory barrier since drm_clflush_virt_range
		   takes care of it.

v4(Michael Cheng): Get the size of value and not the size of the pointer
		   when passing in execlists->csb_write. Thanks to Matt
		   Roper for pointing this out.
