[PATCH 07/10] PM: Export device_pm_schedule_removal

[Greg Kroah-Hartman <gregkh@suse.de>]

From: Rafael J. Wysocki <rjw@sisk.pl>

Move the declaration of device_pm_schedule_removal() to device.h
and make it exported, as it will be used directly by some drivers
for unregistering device objects during suspend/resume cycles in a
safe way.
