David Nieto fe2b83ef4d gpu: nvgpu: refactor interrupt handling ...

JIRA: EVLR-1004

(*) Refactor the non-stalling interrupt path to execute clear on the
top half, so on dGPU case processing of stalling interrupts does not
block non-stalling one.
(*) Use a worker thread to do semaphore wakeups and allow batching of
the non-stalling operations.
(*) Fix a bug where some gpus will not properly track the completion
of interrupts, preventing safe driver unloads
