gpu: nvgpu: Unify remove/shutdown codepaths
The following changes are part of the porting of the bind/unbind
functionality.
These changes reuse the shutdown codepaths in iGPU and dGPU and fix a locking
issue with in gk20a_busy() where the usage count can lead to a deadlock during
the driver shutdown. It fixes a racing condition with the gr/mm code by
invalidating the sw ready flag while holding the busy lock
