usb_hid: mode led handling to shadow input-leds.c
The former implementation relied on input drvdata always pointing to struct hid_device, which is not true for Wacom touch devices (at least). Now, we implement the input handler for devices providing LEDs (evbit[EV_LED] set) only and use input_inject_event() to set the LED states.
