HID: sony: Use LED_CORE_SUSPENDRESUME

commit 765a1077c85e5f2efcc43582f80caf43a052e903 upstream.

The LED subsystem provides the LED_CORE_SUSPENDRESUME flag to handle
automatically turning off and restoring the state of device LEDs during
suspend/resume.  Use this flag instead of saving and restoring the state
locally.
