Add some quirks to make a Shuttle PN-31 remote control work.
Shuttle PN31 remote controls are supposed to act as a USB keyboard and mouse,
but they (in particular the mouse part) don't follow the standards.
5 quirks are needed to get this device to work, 2 of which are unique to this
device so far (it sets a superfluous extra bit on the GenericDesktop keycodes,
and the mouse flags are wrong (_Constant_, Variable, Relative).
Tested with 2.6.16-rc6-mm1 and 2.6.16-rc6-mm2.
