First, both these clocks needs to be documented in DT doc.
Second, I think you should initialize bulk_clks[2|3] to NULL, in case
the new optional clocks can't be fetched.

Another observation is the number of clocks for this device. In some
cases, now six clocks are needed!? Is that really correct? Just wanted
to point it out as it seems a bit too much. :-)
Kind regards
