drm/nouveau/pwr: fix the timers implementation with concurent processes
The problem with the current implementation is that adding a timer improperly
checked which process would time up first by not taking into account how much
time elapsed since their timer got scheduled. Rework the re-scheduling
decision t fix this.
The catch with this fix is that we are limited to scheduling timers of up to
2^31 ticks to avoid any potential overflow. Since we are unlikely to need to
wait for more than a second, this won't be a problem :)
Another possible fix would be to decrement the timeouts of all processes but
it would duplicate a lot of code and dealing with edge cases wasn't pretty
last time I checked.

drm/nouveau/core/mm: fill in holes with "allocated" nodes
The allocation algorithm doesn't expect there to be holes in the mm, which
causes its alignment/cutoff calculations to choke (and go negative) when
encountering the last chunk of a block before a hole.
The least expensive solution is to simply fill in any holes with nodes
that are pre-marked as being allocated.

drm: Only update final vblank count when precise ts is available
Drivers without a hardware vblank counter simply can't account for the
vblanks that happened while the vblank interrupt was off. To check
this grab a vblank timestamp and if the result is dubious follow the
normal save-and-disable logic.
Drivers should prevent this by setting vblank_disable_allowed = false,
but since running vblank interrupts constantly is not good for power
consumption most drivers lie. Testing for precise vblank timestamps is
the next best thing we can check for.
