[PATCH] drm/amdgpu: correct MMSCH version

[Luo, Zhigang]

[AMD Official Use Only]

Yes, the information is from MMSCH firmware team.
They are saying the version info is not used in the old MMSCH firmware, so it won't break the ASICs using old MMSCH firmware.
Ok, I will change the commit message to specify mmsch 1.0.

Thanks,
Zhigang

Is that information from MM team ? 
Please make sure it won't break the ASICs that use the same  code path. Also If this is true for all mmsch_v1.0 , you need to specify this is mmSCH v1.0 , since other MMSCH version will still use this major and  minor.

MMSCH doesn't have major/minor version, only verison.
