We still get spurious pipe underruns on ILK/SNB/IVB under two circumstances when dealing with PCH ports: * When the pipe has been disabled, but FDI RX/TX is still enabled * During FDI link training Both cases seem to happen at least when we do VGA+HDMI cloning from the same pipe. I don't think I've seen them when not cloning, but can't be 100% sure. Disable underrun reporting around those places to eliminate the dmesg errors.
