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.
