HID: hid-input quirk for BTC 8193

BTC 8193 keyboard handles its scrollwheel in very non-standard way.
It produces two non-standard usages for scrolling up and down, in
both cases with postive value equaling to 1. We handle this by temporary
mapping, which we then catch in quirk event handler, and remap to
negative HWHEEL even in order to introduce correct behavior.

Also the button requires special mapping, as it triggers standard-violating
usage code.

Reported in kernel.org bugzilla #9385
