Hi All,

The following two patches are meant to work around a problem where some
devices may be in the ACPI D3cold power state (power off) before their
drivers' .probe() routines are called, but those routines assume devices
to be operational.  They also allow ACPI PM to be used going forward with
the devices in question.

[1/2] - Allow ACPI PM attach/detach routines to change device power states.
[2/2] - Call the ACPI PM attach/detach routines in the platform probe and
        remove/shutdown callbacks (and change power states of devices as
        necessary).

The patches are on top of the current linux-next branch of the linux-pm.git
tree.

Thanks,
Rafael
