[SWDEV-523794] Update to fix MIN_CLK and MAX_CLK incorrect values

(#280)

- Fixed potential issue with min/max values when only one frequency is available
- Improve error handling in GPU frequency range detection
- Refactor clock frequency range detection for better readability
- Added special handling for current frequency indicator (*) in DPM output
- Added comments explaining special case handling for current frequency
- Cleaned up incorrect definitions in hsmp metric table definition
