Subject: [PATCH] drm/amd/pm: Fill metrics data for SMUv13.0.6

Populate metrics data table for SMU v13.0.6. Add PCIe link speed/width
information also.

I see in smu_v13_0.c and smu_v11_0.c, the same macro definitions are present. So is it better to put it into a common place which is scalable for later asics as well?
These are reg offsets and reg field definitions. If there is no change to those offsets/fields we reuse the common smu_v13 or v11 versions for SMU13 or SMU11 family. 

In this case, there is a change.

Thanks,
Lijo
