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. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

If you say Y here, it will be possible to use a 8250/16550 serial
