powerpc/boot: Only build board support files when required.

This is easily reproducible my using the ep88xc_defconfig config file:

arch/powerpc/boot/wrapper.a(mpc8xx.o): In function `mpc885_get_clock':
/home/henrix/src/linux/arch/powerpc/boot/mpc8xx.c:30: undefined reference to `fsl_get_immr' make[1]: *** [arch/powerpc/boot/dtbImage.ep88xc] Error 1
