At least one modern Clevo barebone has the touchpad connected both via PS/2
and i2c interface. This causes a race condition between the psmouse and
i2c-hid driver. Since the full capability if the touchpad is available via
the i2c interface and the device has no external PS/2 port, it is save to
just ignore all ps2 mouses here to avoid this issue.
The know affected device is the Clevo NS70MU.
This patch add a new i8042_dmi_noaux_table with the dmi strings of the
affected device of different revisions. The table is then evaluated like
the other quirk tables in the i8042 driver.
