This change improves the aggressive sync creation
& destruction logic to avoid lock contention in
the submit path. It does the following:
1) Removes the global sync destruction (channel)
threshold, and adds a per-platform parameter.
2) Avoids lock contention in the clean-up/submit
path when aggressive sync destruction is disabled.
3) Creates sync object at gpfifo
allocation time (as long as we are not in aggressive
sync destroy mode), to enable faster first submits

Use struct device instead of struct platform_device wherever
possible. This allows adding other bus types later.
