HID: lenovo: Add support for ThinkPad TrackPoint Keyboard II
This keyboard has two modes: regular HID and a native mode, which is used in Windows driver. Native mode disables (poor) middle mouse button scrolling emulation and reports middle button and scrolling events with a custom report ID, which could be better handled in the driver. This commit adds functional button mapping and native scrolling support. HID collection in Bluetooth mode for custom report ID=5 is broken and is patched upon connection. The collection initially contains incorrect Usage Minimum/Usage Maximum numbers and, more importantly, marks Input as Variable, not Array, while reporting values as in Array. The keyboard is very similar to Compact USB/Bluetooth Keyboard with TrackPoint, that's why this patch reuses all of cptkbd functions, except for input mapping.
