PM: Introduce struct pm_subsys_data
Introduce struct pm_subsys_data that may be subclassed by subsystems to store subsystem-specific information related to the device. Move the clock management fields accessed through the power.subsys_data pointer in struct device to the new strucutre. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
