drm/radeon: Fix sideport problems on certain RS690 boards
commit 8333f0fe133be420ce3fcddfd568c3a559ab274e upstream.
Some RS690 boards with 64MB of sideport memory show up as
having 128MB sideport + 256MB of UMA. In this case,
just skip the sideport memory and use UMA. This fixes
rendering corruption and should improve performance.
