Remove dependency on Jetson (nvgpu) driver internals

For integrated (Jetson) GPUs:
- Directly retrieve and map GPU register region 0
- Directly check GPU power-on state before a register read/write
- Resume the GPU as needed for a register read/write

Most nvgpu APIs can now be called on TX2+ integrated GPUs without
first having to start some task on the GPU to make it non-suspended.

Tested on Jetson TX1, TX2, Xavier, and Orin.
