mb/supermicro/x11ssh: Add Supermicro X11SSH-TF

Add support for the X11SSH-TF which is based on Intel KBL.

Working:
* SeaBIOS payload
* LinuxBoot payload
* IPMI of BMC
* PCIe, SATA, USB and M.2 ports
* RS232 serial
* Native graphics init

Not working:
* TianoCore doesn't work yet as the Aspeed NGI is text mode only.
* Intel SGX, due to random crashes in soc/intel/common

For more details have a look at the documentation.

Please apply those patches as well for good user experience:
