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.
