Subject: [PATCH] drm/amd/pm: set the default workload type to bootup type on smu v13.0.7

Set the default workload type to bootup type on smu v13.0.7.
This is because of the constraint on smu v13.0.7.
Gfx activity has an even higher set point on 3D fullscreen mode than the one on bootup mode. This causes the 3D fullscreen mode's performance is worse than the bootup mode's performance for the lightweighted/medium workload. For the high workload, the performance is the same between 3D fullscreen mode and bootup mode.
