x86, CPA: Add set_pages_arrayuc and set_pages_array_wb
Add new interfaces:
set_pages_array_uc()
set_pages_array_wb()
that can be used change the page attribute for a bunch of pages with
flush etc done once at the end of all the changes. These interfaces
are similar to existing set_memory_array_uc() and set_memory_array_wc().
