    HID: multitouch: Add support for button type usage

    According to [1], Windows Precision Touchpad devices must supply
    a button type usage in the device capabilities feature report. A
    value of 0 indicates that the device contains a depressible
    button (i.e. it's a click-pad) whereas a value of 1 indicates
    a non-depressible button. Add support for this usage and set
    INPUT_PROP_BUTTONPAD on the touchpad input device whenever a
    depressible button is present.
