[PATCH] clk: sunxi-ng: sun5i: Add clk_set_rate_parent to the CPU clock

[PATCH] clk: sunxi-ng: sun5i: Add clk_set_rate_parent to the CPU clock

[Maxime Ripard]

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.
