x86: add early_memremap()
early_ioremap() is also used to map normal memory when constructing the linear memory mapping. However, since we sometimes need to be able to distinguish between actual IO mappings and normal memory mappings, add a early_memremap() call, which maps with PAGE_KERNEL (as opposed to PAGE_KERNEL_IO for early_ioremap()), and use it when constructing pagetables.
