It has been superceded by run-time flag
XENFEAT_auto_translated_physmap.
This patch changes behaviour slightly:
1. set_pmd/set_pgd/set_pud always use mmu_ops, even when
XENFEAT_writable_page_tables is available. Unclear whether
we want to add a test to avoid this.
2. xen_l1_entry_update always uses mmu_op. Again, could gate
this on XENFEAT_writable_page_tables.
3. We always pin/unpin pagetables. Could gate this on a
new XENFEAT flag.
