The documentation in the clk.h file says that clk_get_parent() returns
error pointers but it doesn't. It's also not consistent with the
comments next to the clk_get_parent() implementation which say that
it returns NULL when the clk is NULL. Update the comments so they
are consistent and accurate and say that it returns NULL.
