cpu/x86/pae/pgtbl.c: remove dead map_2M_page()

Browse source 
This function isn't used anywhere. It probably wouldn't work with
current coreboot anyway, as it identity mapped lower 2GB of RAM, while
ramstage is run from CBMEM, which is usually just below top of memory.

It was last used in K8 code that is long gone.
