gpu: nvgpu: support tuning per-ch deterministic opts
Add a new ioctl NVGPU_GPU_IOCTL_SET_DETERMINISTIC_OPTS to adjust
deterministic options on a per-channel basis. Currently, the only
supported option is to relax the no-railgating requirement on open
deterministic channels. This also disallows submits on such channels,
until the railgate option is reset.
