4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexander Syring <alex@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).
