Clean up arch/i386/vmlinux.lds.S

Add some comments indicating read-only, writeable and freed-after-init
sections.

Move .data_nosave, .data.page_aligned, .data.cacheline_aligned next
to the "normal" data area, the only difference this should make, 
apart from being more logical, is a more truthful printk() during boot.
