This structure can be full of junk from the stack if we don't initialize
it. The clk framework tests clk_init_data::parent_names for non-NULL and
then considers that as the parent name pointer, but if it's full of junk
then we'll try to deref a bad pointer and oops the system. Let's
initialize the structure so that only clk_init_data::parent_names or
clk_init_data::parent_data is set, and not both.
