[PATCH v2 00/17] system/physmem: Remove cpu_physical_memory _is_io() and _rw()

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Since v1:
- Removed extra 'len' arg in address_space_is_io (rth)

---

The cpu_physical_memory API is legacy (see commit b7ecba0f6f6):

  ``cpu_physical_memory_*``
  ~~~~~~~~~~~~~~~~~~~~~~~~~

  These are convenience functions which are identical to
  ``address_space_*`` but operate specifically on the system address space,
  always pass a ``MEMTXATTRS_UNSPECIFIED`` set of memory attributes and
  ignore whether the memory transaction succeeded or failed.
  For new code they are better avoided:
  ...

This series removes:
  - cpu_physical_memory_is_io()
  - cpu_physical_memory_rw()
and start converting some
  - cpu_physical_memory_map()
  - cpu_physical_memory_unmap()
calls.
