[PATCH v1 1/3] ARM: rpi: make locally used functions static

[Roland Hieber <rhi@xxxxxxxxxxxxxx>]

These functions are not meant to be a public interface, so they can well
be static. rpi_b_plus_init() was previously declared with a prototype,
which is no longer needed.

This fixes the following build warnings:

    .../arch/arm/boards/raspberry-pi/rpi-common.c:124:6: warning: no previous prototype for 'rpi_add_led' [-Wmissing-prototypes]
     void rpi_add_led(void)
          ^~~~~~~~~~~
    .../arch/arm/boards/raspberry-pi/rpi-common.c:141:6: warning: no previous prototype for 'rpi_b_init' [-Wmissing-prototypes]
     void rpi_b_init(void)
