PM / Runtime: Add subsystem data field to struct dev_pm_info
Some subsystems need to attach PM-related data to struct device and
they need to use devres for this purpose. For their convenience
and to make code more straightforward, add a new field called
subsys_data to struct dev_pm_info and let subsystems use it for
attaching PM-related information to devices.
Convert the ARM shmobile platform to using the new field.
