gpu: nvgpu: initialize ctxsw state for golden context creation
If golden context creation happens before any gpu railgate then
channel creation is always fine. If gpu railgate happens after gpu
finalize poweon, but before golden context creation, then golden
context creation is failing during first channel creation with
watchdog timeout from ctxsw because of invalid ctxsw state.
To Fix this issue, if the golden context is not created, then during
finalize power on always query ctxsw image sizes, which is making ctxsw
hw in correct state before golden context creation.
