[PATCH] Input: i8042 - add TUXEDO BU1406 (N24_25BU) to the nomux list

[Dmitry Torokhov]

TUXEDO BU1406 does not implement active multiplexing mode properly,
and takes around 550 ms in i8042_set_mux_mode(). Given that the
device does not have external AUX port, there is no downside in
disabling the MUX mode.
