[PATCH 4/8] drm/amd/powerplay: add interface for getting workload type

[Wang, Kevin(Yang)]

this patch, i think the smu driver should be unify the driver code format,
it is very useful for optimize and maintain smu driver code in the furture.

you can reference the navi10_ppt.c and arcuturs_ppt.c
funciton: arcturus_get_workload_type

Best Regards,
Kevin
