I don't know if we need to add a cgs call to fill in the 
max_clock_voltage_limits structure.  That's mostly just leftover from radeon.  
A better solution would be use the existing amdgpu_dpm_get_sclk and 
amdgpu_dpm_get_mclk macros.  Maybe something like the attached patch? Unless 
there is a specific need for the max clocks on AC.  I think in most cases the 
results will be the same.

Subject: drm/amd/powerplay: expose max engine and memory clock info for 
powerplay enabled case

Hi All,

We found the max engine clock and max memory clock are both wrongly reported as 
0(by AMDGPU_INFO_DEV_INFO ioctl).
The attached patch tries to fix it.
Please help to review it.
Any comment is welcomed.

Regards,
Evan
