mainboard/siemens/mc_tcu3: Add new mainboard.

This mainboard is based on Intel's Bayleybay
board which uses Bay Trail CPU with Intel FSP.
It has one USB3.0 interface, 4 USB2.0 interfaces,
up to two Ethernet ports and a LVDS connection
for LCD panels. The board is equipped with 512 MB
of DDR3 in a memory down configuration.

This board boots into Ubuntu/Lubuntu 14.10 using SeaBIOS,
but other OSes should work as well (but are not tested).
It has a version.hex file which is needed for
our OS and has no hardware functionality.
