This patch adds the infrastructure to define different config headers with different configurations and default environment for the baseboards that can now be selected via Kconfig. The new configuration for the theadorable-x86-conga-qa3-e3845 is also added. Also the new defconfig file for this new target is added.

------------------------------ U-Boot console UART selection: ------------------------------ The U-Boot port for this congatec board currently supports two different configurations (defconfig files). The only difference is the UART that is used as the U-Boot console UART. The default defconfig file: conga-qeval20-qa3-e3845_defconfig provides this console on the UART0 which is provided via a Winbond Super-IO chip connected on the congatec Qseven 2.0 evaluation carrier board (conga-QEVAL). This UART is the one provided with a SubD9 connector on the mainboard (the low one). The 2nd defconfig file: conga-qeval20-qa3-e3845-internal-uart_defconfig provides the U-Boot console on the BayTrail internal legacy UART, which is routed from the QSeven SoM to the X300 connector on the baseboard. Here is called COM2. The baseboard already provides the RS232 level shifters. So a TTL-USB UART adapter does not work in this case. The signals need to get connected directly to the RS232 level signals of the PC UART via some adapter cable.
