- 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.
