MIPS: Fix build error due to multiple prom_putchar() definitions.
This can happen if both the generic 8250 and another early console
driver are enable. Fixed by using an auxilliary kconfig symbol to
restrict that choice.

If you say Y here, it will be possible to use a 8250/16550 serial
port as the boot console.
