[PATCH V2 18/29] staging: bcm2835-camera: Add multiple inclusion protection to headers

[Stefan Wahren <wahrenst@gmx.net>]

From: Dave Stevenson <dave.stevenson@raspberrypi.org>

mmal-common.h and mmal-msg.h didn't have the normal
ifndef FOO / define FOO / endif protection to stop it being
included multiple times. Add it.
