tegra: hwpm: Add support for next3 chip

Browse Source 
- This patch adds the support for next3 chip in the hwpm kernel repo.
- Add NULL check for fake registers before read/write operations.
- On simulation platform, HWPM allocates memory to simulate perfmux and
perfmon address spaces. Update IP instance mask logic to assume perfmux
is available.
