arch/x86: Add array variants for setting memory to wc caching.
Setting single memory pages at a time to wc takes a lot time in cache flush. To
reduce number of cache flush set_pages_array_wc and set_memory_array_wc can be
used to set multiple pages to WC with single cache flush.
This improves allocation performance for wc cached pages in drm/ttm.
