Since the PM clock management code in drivers/base/power/clock_ops.c is used for both runtime PM and system suspend/hibernation, the definitions of data structures and headers related to it should not be located in include/linux/pm_rumtime.h. Move them to a separate header file. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
