Adds support for the X-Box Adaptive Controller, which is protocol
compatible with the XTYPE_XBOXONE support in the driver with two deltas:
- The X-Box button sets 0x02 as its activation ID, where others set
0x01
- The controller has an additional "Layer" button with 4 active states,
which this change maps to an Axis control with 4 possible values
