drivers/uart/Kconfig: Be smarter about DRIVERS_UART_8250IO

It defaults to y to avoid having to select it per mainboard. But that
makes a mess because it results in linker conflicts unless other UART
drivers disable it explicitly.

We try to be smarter about the default value for now. The real solu-
tion would be to hardcode it per mainboard. But who knows which boards
actually have it?
