HID: amd_sfh: Add physical location to HID device

when HID device is loaded a wrong string is shown as
physical location is not declared.
```
hid-generic 0020:1022:0001.0009: hidraw4: <UNKNOWN>
	 HID v0.00 Device [hid-amdtp 1022:0001] on
```

Hence use amd sfh driver name or device name which is connected
to the HID device.
