HID: quirk for Saitek RAT7 and MMO7 mices' mode button
Some saitek mice implement a tristate button (for switching button mappings in
the original driver) by keeping one of three (non-physical)
buttons constantly pressed.
This breaks X and probably other userspace software.
This patch implements a quirk for the R.A.T.7 and M.M.O.7, tracking the mode
and generating presses of a single button if it changes. Also the missing
release event is generated instantly.
