HID: amd_sfh: Add support for shutdown operation 



As soon as the system is booted after shutdown, the sensors may remain in
a weird state and fail to initialize. Therefore, all sensors should be
turned off during shutdown.

Fixes: 4f567b9f ("SFH: PCIe driver to add support of AMD sensor fusion hub")
