This is a split-up of:
    [PATCH-for-4.2 v1 3/9] s390x/mmu: DAT translation rewrite
Rebased on latest upstream changes. Hopefully, this makes it easier to
review.

v2 -> v3:
- "s390x/mmu: Inject PGM_ADDRESSING on boguous table addresses"
-- Keep using cs->as
-- Make read_table_entry() return true/false
- "s390x/mmu: DAT table definition overhaul"
-- Added a comment where to find details about s390x and used definitions

v1 -> v2:
- Cleanup old code first, before switching to non-recursive handling
- Fix EDAT1 translation: I was missing the vaddr offset within the 1MB
  page.
