drm: Add DRM_DEBUG_VBL()
Add a new debug class for _verbose_ debug message from the vblank code.
That is message we spew out potentially for every vblank interrupt.
Thierry already got annoyed at the spew, and now I managed to lock up
my box with these debug prints (seems serial console + a few debug
prints every vblank aren't a good combination).
Or should I maybe call it DRM_DEBUG_IRQ?
