Move vblank data allocation to happening at attach, not at irq enable.
just put a vblank_pipes argument to the driver structure which tells us
how many to set up
this means that intel doesn't lose all vblank count on vtswitch (it
disables the interrupt there), i've heard of a few uvm_faults where this
happens as well as things just going wrong.
This was suggested by Keith Packard who provided a different diff for
drm.git.
