[PATCH v1 2/3] mci: bcm2835: make locally used functions static

[Roland Hieber <rhi@pengutronix.de>]

The mci-bcm2835 driver registers itself as an MCI driver on probing, and
is thereby used through the MCI interface, so these functions are not
meant to act as a public interface and only used internally in this
compilation unit.

This fixes the following build warnings:
