[PATCH 4.14 16/22] clk: sunxi-ng: Fix missing CLK_SET_RATE_PARENT in ccu-sun4i-a10.c

[Greg Kroah-Hartman]

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

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

From: Alexander Syring <a...@asyring.de>

commit a894990ac994a53bc5a0cc694eb12f3c064c18c5 upstream.

When using cpufreq-dt with default govenor other than "performance"
system freezes while booting.
Adding CLK_SET_RATE_PARENT | CLK_IS_CRITICAL to clk_cpu fixes the
problem.

Tested on Cubietruck (A20).
