x86: conga-qeval20-qa3: Add support for internal UART
This patch adds support to enable and use the internal BayTrail UART
instead of the one integrated in the Super IO Winbond chip. For this,
a 2nd defconfig file is added.
This is useful for tests done for the congatec SoM used on baseboards
without such a Super IO chip.
