- 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.

- Some of the APIs are not available on stable kernel. Use kstable
specific APIs with LINUX_KERNEL macro condition.
- Temporarily comment functions that are not available on Kstable.
- Next chip headers are renamed to accommodate more than one next chip.
Update next chip includes in init.c and driver.c files.
- Rename TEGRA_SOC_HWPM_IP_INACTIVE to TEGRA_HWPM_IP_INACTIVE to follow
other macro/enum naming convention.
- Use is_resource_active() HAL instead of chip specific function.
- Create clock reset functions that will allow us to handle change in
APIs on kstable.

Currently, linux specific SOC functions below are used in HWPM driver.
- find type of platform/config
- read fuse registers
- read device info
In order to make HWPM OS agnostic, add wrappers for SOC functions and/or
move code to os folder.
