None of these prototypes should be needed, most functions are never
called outside of their units and are just missing a static
annotation, and one already has a prototype in a different header.

This one already has a prototype in bcm63xx_dev_uart.h,
arch/mips/bcm63xx/dev-uart.c just needs to include that header file.
