drm/amd/pm:add new gpu_metrics_v2_3 to acquire average temperature info

Browse Source 
Add new gpu_metrics_v2_3 to acquire average temperature info from SMU metrics. To acquire average temp info from gpu_metrics interface, but gpu_metrics_v2_2 only has members to show current temp info.
---
v1:
	Only add average_temperature_gfx in gpu_metrics_v2_3.
v2:
	Add average temp members for soc, core and l3 in gpu_metrics_v2_3 and put these new members at the end of gpu_metrics_v2_3. Add operation to read average temp info from metrics table.
v3:
	Merge v1 and v2 and rename the patch.
v4:
	Merge v3. Add firmware version judgment in vangogh_common_get_gpu_metrics to maintain backward compatibility and rename the patch. "return ret" on error scenario in smu_cmn_get_smc_version.
