The definitions from console.h are not needed in the bcm2835_fb.h header file yet, so let's move it to the place that really needs its definitions, i.e. into the bcm2835_fb.c file. This way the header can also be used by code that is not compiled with the CFLAGS that are required for pixman or OpenGL (in case their headers do not reside under /usr/include).
