HID: lenovo: Add support for Thinkpad X1 Tablet Thin keyboard
The Thinkpad X1 Tablet Thin keyboard's HID interface for the media-keys and other special functions, is quite similar to the Thinkpad 10 ultrabook keyboard's mouse/media-keys HID interface. The only difference is that it needs a bit different key mappings. Add support for the mute-LED and the non-standard media-keys on this keyboard by re-using the tp10_ultrabook_kbd code combined with a new lenovo_input_mapping_x1_tab_kbd() function.
