4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Maxime Ripard <maxime.rip...@free-electrons.com>

commit 9735ee9e3cc3ba113ac96b0368ef3f1a73092a23 upstream.

The current CPU clock is missing the option to change the rate of its
parents, leading to improper rates calculated by cpufreq, and eventually
crashes.

Fixes: 5e73761786d6 ("clk: sunxi-ng: Add sun5i CCU driver")
