From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Follow previous commit 9a0abc39450a ("PM: runtime: Add auto-cleanup
macros for "resume and get" operations") and define a runtime PM
usage counter guard in which pm_runtime_get_noresume() and
pm_runtime_put_noidle() will be used for incrementing and
decrementing it, respectively.
