tegra: hwpm: add support for next2 chip

- add next2 init chip info logic
- add next2 device id
- Update logic of chip info functions to support next2 chip. Modify the
functions to use formal "if defined()" macro instead of "ifdef".
- Execute support-soc-tools property only on silicon platform
- Separate OOT module_init symbol from postcore_init call on previos
kernel.
