Hacky support for Linux 5.6+ and the Jetson AGX Orin

Works around change in parameters to proc initialization functions
via a hacky function which rewrites the layout. This also required
making all the struct file_operations writable.

Also start reducing dependency on nvgpu headers.

Known issues:
- Incorrect message printed in log after module is loaded. Unclear
  if this is because the register detection logic is broken, or if
  the layout of the data at NV_MC_BOOT_0 has changed.
- Not tested
