x86: conga-qeval20-qa3: Add support for internal UART

Browse Source 
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.
