  Fix the name of the dts file for the HL201...

  When mapping an address, the bsh needs the same offset we do for other things.

  Add explicit depends on bus_if.h and device_if.h to avoid a
  chicken and egg problem in some compilation environments.

  Switch to using PAs rather than VAs for the addresses we map for
  devices. This is a nop, except for what's reported by atmelbus for the
  resources.

  Comment cleanups.  Move things around for diff reduction against FDT work.
