[PATCH 1/3] drm/radeon/kms: add some loop timeouts in pageflip code

I've tested all three patches in this series, on an AMD E-350 platform. 1/3 is essential to prevent a complete system hang if the GPU needs resetting during a page flip; the disaster case is this endless loop running on core 0, and RCU on core 1 waiting for core 0 to idle. The remaining two need
