PM: Introduce struct pm_subsys_data

Browse Source 
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.
