Jiri Kosina 25914662b7 HID: fix Logitech DiNovo Edge touchwheel and Logic3 /SpectraVideo middle button 
Dongle shipped with Logitech DiNovo Edge (0x046d/0xc714) behaves in a weird
non-standard way - it contains multiple reports with the same usage, which
results in remapping of GenericDesktop.X and GenericDesktop.Y usages to
GenericDesktop.Z and GenericDesktop.RX respectively, thus rendering the
touchwheel unusable.

The commit 3506897691 solved this
in a way that it didn't remap certain usages. This however breaks
(at least) middle button of Logic3 / SpectraVideo (0x1267/0x0210),
which in contrary requires the remapping.

To make both of the harware work, allow remapping of these usages again,
and introduce a quirk for Logitech DiNovo Edge "touchwheel" instead - we
disable remapping for key, abs and rel events only for this hardware.
