    HID: logitech-hidpp: add support for HID++ 1.0 wheel reports · 4a79bcc6

    Add a quirk for switching wheel event reporting to using the HID++
    report for this.
    
    This has 2 advantages:
    1) Without this tilting the scrollwheel left / right will send a
       scroll-lock + cursor-left/-right + scroll-lock key-sequence instead of
       hwheel events
    
    2) The HID++ reports contain the device index instead of using the generic
       HID implementation, so this will make scroll-wheel events from the wheel
       on some keyboards be emitted by the right event node.
    
    2. also fixes keyboard scroll-wheel events getting lost in the (mostly
    theoretical) case of there not being a mouse paired with the receiver.
    
    This commit enables this quirk for all 27Mhz mice, it cannot hurt to have
    it enabled and this avoids the need to keep adding more and more quirks for
    this. This has been tested in 5 different 27MHz mice, 3 of which have a
    wheel which can tilt.
    
    This commit also adds explicit quirks for 3 keyboards with a zoom-/scroll-
    wheel. The MX3000 keyboard scroll-wheel can also tilt. I've defined aliases
    to the new HIDPP_QUIRK_HIDPP_WHEELS for this, so that it is clear why the
    keyboard has the quirk and in case we want to handle the keyboard wheels
    and especially the keyboard zoom-wheels differently in the future.
