drivers: base: power: add proper SPDX identifiers on files that did not have them. There were a few files in the driver core power code that did not have SPDX identifiers on them, so fix that up. At the same time, remove the "free form" text that specified the license of the file, as that is impossible for any tool to properly parse. Cc: "Rafael J.

PM: Provide generic subsystem-level callbacks There are subsystems whose power management callbacks only need to invoke the callbacks provided by device drivers. Still, their system sleep PM callbacks should play well with the runtime PM callbacks, so that devices suspended at run time can be left in that state for a system sleep transition. Provide a set of generic PM callbacks for such subsystems and define convenience macros for populating dev_pm_ops structures. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

drivers/base: Add export.h for EXPORT_SYMBOL/THIS_MODULE as required. Most of these files were implicitly getting EXPORT_SYMBOL via device.h which was including module.h, but that path will be broken soon.

PM / Runtime: Implement the pm_generic_runtime functions for CONFIG_PM The pm_generic_runtime_suspend|resume functions were implemented within CONFIG_PM_RUNTIME. As we also may use runtime PM callbacks during system suspend, to put devices into low power state, we need to move the implementation of pm_generic_runtime_suspend|resume to CONFIG_PM. This change gives a power domain provision to invoke a platform driver's runtime PM callback from a power domain's system PM callback. This were earlier prevented by the platform bus, since it uses the pm_generic_runtime_suspend|resume functions as runtime PM callbacks.

PM / Runtime: Lenient generic runtime pm callbacks Allow drivers, that belong to subsystems which use the generic runtime pm callbacks, not to define runtime pm suspend/resume handlers, by implicitly assuming success in such cases. This is needed to eliminate nop handlers that would otherwise be necessary by drivers which enable runtime pm, but don't need to do anything when their devices are runtime-suspended/resumed.

PM: Provide generic subsystem-level callbacks There are subsystems whose power management callbacks only need to invoke the callbacks provided by device drivers. Still, their system sleep PM callbacks should play well with the runtime PM callbacks, so that devices suspended at run time can be left in that state for a system sleep transition. Provide a set of generic PM callbacks for such subsystems and define convenience macros for populating dev_pm_ops structures. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
