drm/amdgpu/powerplay/smu7: fix AVFS handling with custom powerplay table
When a custom powerplay table is provided, we need to update the OD VDDC flag to avoid AVFS being enabled when it shouldn't be. Bug: https://bugzilla.kernel.org/show_bug.cgi?id=205393 Reviewed-by: Evan Quan <evan.quan@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
