Hello Alex and Michel,

isn't this needed anylonger?

Subject: drm/radeon: Disable pflip interrupts

With Mario's previous fix, there are three possible scenarios for the
pflip interrupts:

1) If a pflip interrupt can occur before the corresponding vblank
    interrupt, the sequence number of the userspace event will be too
    small by one.
2) If a pflip interrupt can occur after the vblank interrupt and after
    the next flip is programmed to the hardware, 
radeon_crtc_handle_flip()
    will complete the next flip earlier than expected by userspace.
3) Otherwise, radeon_crtc_handle_flip() doesn't perform any actual work
    when called from the pflip interrupt handler, i.e. the pflip 
interrupt
    is useless.

In summary, Mario's fix made the pflip interrupts useless in the best
case and harmful in the worst case, so let's disable them.
