  - Don't shift the clock frequency in MHz left by 8 before assigning it
    to sbus_mdvec.dv_clock as sbus_mdvec.dv_clock is meant to be specified
    in MHz. While this was a bug it shouldn't have affected FreeBSD/sparc64
    as sbus_mdvec.dv_clock is used to limit the clock rate of chips when
    a machine isn't able to support them at maximum speed which isn't the
    case for sun4u machines.
  - Remove the code that checks whether the clock frequency returned by
    sbus_get_clockfreq() is 0 and falls back to 25MHz if it is as that's
    already done in sbus(4).
