Detail:
  s/ARMops - If extended pages aren't supported, make sure we use a PCBTrans table which doesn't use L2_X, otherwise the AP flags for some of the sub-pages will be corrupted when the PCB flags get merged in. Add some more comments to the PCBTrans tables so it's easier to see what the different columns are.
  s/ARM600 - Fix BangCam to use extended pages if they're supported; otherwise (assuming ARMops has selected the right PCBTrans table) we'll end up corrupting the AP flags again
  s/HAL - Fix ConstructCAMfromPageTables using the wrong register for ZeroPage when looking up MMU_PCBTrans. Correct a few comments.

  Tested on Iyonix
  Page table examination now shows that all subpages have the correct (i.e. identical) AP flags. Previously some pages would have incorrect access (e.g. every 4th subpage in some FileCore disc map/dir buffer DAs were writable in user mode)
  ARMops fix will presumably mean extended pages will now work correctly on IOP 80200, as before it would have been using small pages with corrupt AP flags
