While testing on Renesas RZ/G2E platform, noticed the clock frequency to
be 24242424 as a result the probe failed. However increasing the maximum
leverage of external clock frequency to 24480000 fixes this issue. Since
this difference is small enough and is insignificant set the same in the
driver.
