Vedashree Vidwans 705bd5ac75 tegra: hwpm: add chip_info support for OOT
- Currently, kernel OOT doesn't support chip id info functions.
Introduce hwpm_soc_chip_info structure that holds soc info required by
the driver.
- Add function to initialize the chip info. Rename previous
tegra_hwpm_init_chip_info to tegra_hwpm_get_chip_info to avoid confusion
of the functionality.
- Implement tegra_hwpm_init_chip_info to initialize chip info structure
when OOT kernel is used. The implementation supports both ACPI and
device tree.
- Separate all chip info functions implementations for OOT kernel and
previous kernels. This cleans up the file and makes code more legible.
- Currently, tegra_hwpm_read_support_soc_tools_prop is only implemented
if device trees are accessible by the driver. Hence add condition to
execute the function only if ACPI is not supported.
- Add ACPI device table reference in the driver.
- Rename tegra_hwpm_next1_init_chip_info to
tegra_hwpm_next1_init_chip_ip_structures and similarly for all future
chips.
