from mainline-master
commit 3d845d49
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I475PF?from=project-issue
CVE: NA

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

Kunpeng930 sec device supports dynamic clock gating. When doing tasks,
the algorithm core is opened, and when idle, the algorithm core is closed.
This patch enables sec dynamic clock gating by writing hardware registers.
