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

[ Upstream commit a4c2a13129f7c5bcf81704c06851601593303fd5 ]

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.
