mb/supermicro/x11ssh-tf: Disable i8042 support 

Even though the vendor firmware enables the i8042 I/O port, it doesn't
feed valid data to those, but instead uses USB HID devices.

Disable the KBC port in SuperI/O and report no KCS port using FADT.

Fixes:
* Fixes error message in Linux that i8042 keyboard couldn't be enabled.

Tested on Supermicro X11SSH-TF:
The virtual remote managment console still works.
