x86: unify paravirt pagetable accessors
Put all the defines for mapping pagetable operations to their native
versions (for the non-paravirt case) into one place. Make the
corresponding changes to paravirt.h.
The tricky part here is that when a pagetable entry can't be updated
atomically (ie, 32-bit PAE), we need special handlers for pte_clear,
set_pte_atomic and set_pte_present. However, the other two modes
don't need special handling for these, and can use a common
set_pte(_at) path.
