This is necessary to prevent concurrent jobs from messing up class state. This has not been necessary so far since due to our channel allocation model, there has only been a single hardware channel submitting commands to each class. Future patches, however, change the channel allocation model to allow hardware-scheduled concurrency, and as such we need to start locking. This patch implements locking on all platforms from Tegra20 to Tegra186.
