efifb: Enable write-combining Running fbcon on an uncached framebuffer is remarkably slow. So try to enable write combining in efifb. Without this patch, it takes 5.8 seconds from efifb probe to i915 probe (default options; no plymouth or quiet mode). With this patch, it only takes 1.7 seconds. That means we wasted over 4 seconds just writing to UC memory.
