PM / devfreq: Adjust default HiSilicon uncore devfreq polling interval and workqueue 

hulk inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/IBC4SJ



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

The uncore frequency adjustment configuration takes effect at the
millisecond level, and the status of devices within the uncore range
fluctuates greatly.

Increase the polling interval to reduce the impact of the frequency
adjustment effective time and smooth the device status fluctuation.
