This came up recently, where there was some confusion around the
!coh_mode checking, for hw reserved PAT index. Series removes that
completely and just uses pat.valid.

v2:
  - Update the kernel-doc to reflect the behaviour change in
    get_coh_mode().
  - With that we should then harden everything else and
    make this consistent. Add a new patch for this.
v3:
  - Improve is_valid() to return false for out-of-range (Tejas).
