  PM / devfreq: Add HiSilicon uncore frequency scaling driver (2025-07-14 20:23:57 +0900)

----------------------------------------------------------------
Update devfreq next for v6.17

Detailed description for this pull request:
- Clean devfreq core and fix bugs
 : Replace sscanf with kstrtoul
 : Remove redundant devfreq_get_freq_range() on adding devfreq driver
 : Check missing NULL pointer check on removing devfreq driver
 : Limit max_freq and min_freq to avoid unreachable value
 : Fix wrong index on trans_stat sysfs node

- Use devm_* managed function for clock control on sun81-a33-mbus driver

- Add HiSilicon uncore frequencye scaling driver for for HiSilicon Kunpeng SoCs
 : The uncore domain includes shared system resources such as interconnects
 and L3 cache, and its frequency has a significant impact on system performance
 and power consumption. The driver provides the following functions:
   - Support to scale frequency scaling with governor and user setting
   - Support to query CPUs whose performance is closely related to the uncore domain
   - Communication with the platform controller via an ACPI PCC mailbox
     to perform actual frequency changes
