if user select manual dpm mode,we will disabe autowattman.
When switch to auto, we will restart the auto wattman on Polaris,
Restore to default profile mode on other ASICS.


Best Regards
Rex

Would be good to give a brief description of what autowattman actually
does in the patch description.  Also, we may need to manually select a
profile in some cases (e.g., VR).  Would that be a problem with
autowattman?
