drm/amd/pm: update dpm clock pm attributes for aldebaran (gc 9.4.2)
v1:
Separate DPM clock attribute constraints for Arcturus (9.4.1) and
Aldebaran (9.4.2) ASICs.
- For Aldebaran:
* mclk/socclk: Disable write, only voltage control supported
* fclk/pcie: Mark as unsupported
- Remove 9.4.2 from global pcie check and handle it in ASIC specific case
- Update comments to reflect correct hardware names
v2:
fix some coding logic issue (by asad)
