PM: Add EXPORT macros for exporting PM functions
Add a pair of macros for exporting functions only if CONFIG_PM
is enabled.
The naming follows the style of the standard EXPORT_SYMBOL_*()
macros that they replace.
Sometimes a module wants to export PM functions directly to other
drivers, not a complete struct dev_pm_ops. A typical example is
where a core library exports the generic (shared) implementation
and calling code wraps one or more of these in custom code.
