Maxime Ripard 9735ee9e3c clk: sunxi-ng: sun5i: Add clk_set_rate_parent to the CPU clock
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.

Cc: <stable@vger.kernel.org>
Fixes: 5e73761786 ("clk: sunxi-ng: Add sun5i CCU driver")
