Input: i8042 - add Fujitsu Lifebook E5411 to i8042 quirk table

In the initial boot stage the integrated keyboard of Fujitsu Lifebook E5411
refuses to work and it's not possible to type for example a dm-crypt
passphrase without the help of an external keyboard.

i8042.nomux kernel parameter resolves this issue but using that a PS/2
mouse is detected. This input device is unused even when the i2c-hid-acpi
kernel module is blacklisted making the integrated ELAN touchpad
(04F3:308A) not working at all.

Since the integrated touchpad is managed by the i2c_designware input
driver in the Linux kernel and you can't find a PS/2 mouse port on the
computer I think it's safe to not use the PS/2 mouse port at all.
