A helper that drivers can use to send vblank event after a pageflip.
If the driver doesn't support proper vblank irq based time/seqn then
just pass -1 for the pipe # to get do_gettimestamp() behavior (since
there are a lot of drivers that don't use drm_vblank_count_and_time())
Also an internal send_vblank_event() helper for the various other code
paths within drm_irq that also need to send vblank events.
v1: original
v2: add back 'vblwait->reply.sequence = seq' which should not have
been deleted
v3: add WARN_ON() in case lock is not held and comments
v4: use WARN_ON_SMP() instead to fix issue with !SMP && !DEBUG_SPINLOCK
as pointed out by Marcin Slusarz
v5: update docbook
