This patches are for Xen-unstable and Qemu-DM.

With the integration of Xen into QEMU, we would like to minimise the change
and use the ACPI implementation of QEMU. So there are some change to make on
the firmware to match the QEMU's BIOS. Some IO Ports are different and the
sleep state values are different.

Changhe v3->v4:
  - Rename HVM_PARAM_ACPI_NEW_IOPORT to HVM_PARAM_ACPI_IOPORTS_LOCATION
  - Better comment for HVM_PARAM_ACPI_IOPORTS_LOCATION.

Change v2->v3:
Xen will register the old ioport by default and switch to the new ioport if the
HVM_PARAM_ACPI_NEW_IOPORT is set. So, this series come with a new function,
unregister_io_handler, and a new HVM_PARAM.

Change v1->v2:
This time, both old and new ioport are handled.
In QEMU-Xen, the choice between one or the other is made when a saved state is
restored.
In Xen, both ioports are registered.

Anthony PERARD (5):
  firmware, Change ACPI IO addresses and values to match QEMU BIOS.
  xen, Introduce unregister_io_handler
  xen, Introduce pmtimer_change_ioport and
    HVM_PARAM_ACPI_IOPORTS_LOCATION.
  firmware, Set HVM_PARAM_ACPI_IOPORTS_LOCATION
  libxc, save/restore, Save the HVM_PARAM_ACPI_IOPORTS_LOCATION
