Input: i8042 - add Thinkpad R31 to nomux list

commit 5bd8a05e937b3ab88cd7ea569e32738f36c42bd0 upstream.

Thinkpad R31 needs i8042 nomux quirk.  Stops jittery jumping mouse
and random keyboard input. Fixes kernel bug #11723.  Cherry picked
from Ubuntu who have sometimes (on-again-off-again) had a fix in
their patched kernels.
