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?
