drm/amdgpu: disable workload profile switching when OD is enabled

Browse Source 
Users have reported that they have to reduce the level of undervolting
to acheive stability when dynamic workload profiles are enabled on
GC 10.3.x. Disable dynamic workload profiles if the user has enabled
OD.

Fixes: b9467983b7 ("drm/amdgpu: add dynamic workload profile switching for gfx10")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4262
