Subject: drm/radeon: KV has three PPLLs (v2)
From: Alex Deucher <alexander.deucher@xxxxxxx>
commit fbedf1c3fc3a1e9f249c2efe2f4553d8df9d86d3 upstream.
Enable all three in the driver. Early documentation
indicated the 3rd one was used for something else, but
that is not the case.
v2: handle disable as well
