Also print VCE clocks in amdgpu_pm_info.

power2_cap_default/min/max only represent second level limits

- PPSMC_MSG_ResetVCN (0x5E)
- Updates PPSMC_Message_Count to 0x5F to account for new messages
2. Adding message mapping for ResetVCN in smu_v13_0_12_ppt.c:
- Maps SMU_MSG_ResetVCN to PPSMC_MSG_ResetVCN
These changes enable proper VCN reset handling through the SMU firmware
interface for compatible AMD GPUs.
