Sorry I didn't notice this before, but we don't need/want to have
NULL terminated entries because it requires the first element to
be non-zero for all valid entries and also wastes space in each
parent map array. We already know that a particular clock has N
number of parents and we can query that from the framework, so we
should use __clk_get_num_parents() to figure out how many times
to loop.

This doesn't seem to be NULL terminated anyway.
