arm: tegra: nvhost: Add debugfs entry for null GPU kickoff
Add a debugfs entry for enabling/disabling GPU null kickoff of
graphics submits on a per process basis.
Restructure existing tegra_host debugfs node by making the existing
tegra_host file a directory and moving the status query under its own
status node. Thus the file system structure changes from:
/sys/kernel/debug/tegra_host - status
to
/sys/kernel/debug/tegra_host/status - status
/sys/kernel/debug/tegra_host/null_kickoff_pid - null GPU ctl
