drm/radeon/kms: fix crtc vblank update for r600
In 2.6.32.2 r600 had no IRQ support, however the patch in
500b758725314ab1b5316eb0caa5b0fa26740e6b to fix vblanks on avivo
cards, needs irqs.
So check for an R600 card and avoid this path if so.
This is a stable only patch for 2.6.32.2 as 2.6.33 has IRQs for r600.
