clk: update clk_clean_rate_cache to use private clk struct

In clk_clean_rate_cache, clk->rate should update the private clock
struct, in particular when CCF is activated, to save the cached
rate value.

When clk_get_parent_rate is called, the cached information
is read from pclk->rate, with pclk = clk_get_parent(clk).

As the cached is read from private clk data, the update should
be done also on it.
