[PATCH] drm/amdgpu: Enable SMU 13.0.0 optimizations when ROCm is active (v2)

[Alex Deucher]

From: Kun Liu <Kun.Liu2 at amd.com>

When ROCm is active enable additional SMU 13.0.0 optimizations.
This reuses the unused powersave profile on PMFW.

v2: move to the swsmu code since we need both bits active in
    the workload mask.
