gpu: nvgpu: add sched domain bind ioctl

Browse Source 
Support binding TSGs to some other scheduling domain than the default
one. Binding happens by name until a more robust interface appears in
the future, as the name is a natural identifier for users.

No other domains are actually created anywhere yet; that will happen in
next patches.
