USB / PM: Drop CONFIG_PM_RUNTIME from the USB core
After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so quite a few depend on CONFIG_PM (or even dropped in some cases). Replace CONFIG_PM_RUNTIME with CONFIG_PM in the USB core code and documentation. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
