[PATCH 1/2] drm/amd/pm: Add information about SMU11 firmware version

[Liang, Prike]

[Public]

In the SMU issue troubleshooting process we also can check the SMU version by reading MP1 scratch register and  from long term we may need put the SMC version collection in the debug sysfs amdgpu_firmware_info.

In this patch fashion, we better use dev_dbg instead of dev_info for only debug purpose.
