x86: baytrail: Introduce a Kconfig option for the internal UART
There are quite a number of BayTrail boards that uses an external SuperIO chipset to provide the legacy UART. For such cases, it's better to have a Kconfig option to enable the internal UART. So far BayleyBay and MinnowMax boards are using internal UART as the U-Boot console, enable this on these two boards.

+ There is a legacy UART integrated into the Bay Trail SoC.
+ A maximum baud rate of 115200 bps is supported. For this
+ reason, it is recommended that the UART port be used for
+ debug purposes only, eg: U-Boot console.
