Update devfreq for 5.5-rc2

Browse source 
Detailed description for this pull request:
 1. Update devfreq core
 - Add PM QoS support for devfreq device with following QoS type. External user
 of devfreq device can request the minimum and maximum frequency according to
 their multiple requirements.
 : DEV_PM_QOS_MIN_FREQUENCY is used for requesting the minimum device frequency.
 : DEV_PM_QOS_MAX_FREQUENCY is used for requesting the maximum device frequency.
 
 - Use PM QoS interface when entering the min/max_freq via sysfs interface.
 
 - Add get_freq_range() helper function in order to get the final min/max
 frequency among the multiple requirements of min/max frequency.
 
 - Fix the issue such as fixing the return value and modify code
 for more correct exception handling if error happen.
