soc/intel: Replace UART_BASE() and friends with a Kconfig

Re-add the Kconfig CONSOLE_UART_BASE_ADDRESS. It was lost by accident
on APL at least. It is used outside of soc/intel/ scope, e.g. to con-
figure SeaBIOS.

As we only ever configure a single UART for the coreboot console, we
don't need different addresses for each possible UART. Which saves
us a lot of code.
