1. SVS driver uses OPP adjust event in [1] to update OPP table voltage part.
2. SVS driver gets thermal/GPU device by node [2][3] and CPU device by
get_cpu_device(). After retrieving subsys device, SVS driver does
device_link_add() to make sure probe/suspend callback priority.
3. SVS dts refers to reset controller [4] to help reset SVS HW.

changes since v10:
- Fix typos and remove duplicate GENASK()
- Use DIV_ROUND_UP instead of creating own math
- Remove fake_efuse related codes and some type casting
- Optimize svs_get_vops_v2() coding
- Check "supplier links.status DL_DEV_DRIVER_BOUND" to make
sure supplier is ready after doing device_link_add()
