misc: mods: Add support for AON invocation

Browse Source 
- Enable MODS kernel driver ADSP APIs
- Updated CONFIG_TEGRA_NVADSP to MODS_HAS_TEGRA
- get_handle call is invoked for each API
      - To avoid regression on parallel WAT testing
- Fork nvidia-oot from nvidia-kernel
      - Firmware APIs do not support 5.1 version.
- Updating the same IOCTLs as its being used by AON and ADSP tests.
