Not anymore, now clk->name is gone ;-)

As a driver writer, once in a while I need to print out names and rates for
clocks and their parents from driver debug code.
As before this involved including clk_private.h and having #ifdefs to
support both
legacy and CCF, that debug code was alwas stripped from drivers before
submission, and never went upstream.

If someone feels the need to print those, support can be added.
