[rpi3][bcm28xx][timer] Fix BCM2837 timer runing too fast.
RPi3/BCM2837 timer was previously running too fast due to an improper multiplier
in arm_generic_timer_init(...). Fixed by setting the multiplier to 0 and
allowing the ARM generic timer code to determine the frequency and compute the
appropriate multiplier.
