- 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.

- 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.

Fix bugs for accessing uninitialized mem_mgmt and alist_map structures.
- Not initializing memory management functionality in HWPM is a valid
situation. Currently, tegra_hwpm_clear_mem_pipeline dereferences the
mem_mgmt pointer without validation, which can lead to failures. Check
if mem_mgmt struct pointer is valid before dereferencing.
- Alist_map structure is only required if user requests allowlist size
or list of allowlist registers. Currently, tegra_hwpm_sw_setup
dereferences alist_map pointer to set full_alist_size to 0. Add
alist_map allocation function and set full_alist_size to 0.
- Add PMA and CMD_ROUTER as valid cases for
tegra_hwpm_translate_soc_hwpm_resource() translation.
- Move logic to record IP function pointers to separate function. This
way changes to IP ops registration will be in single location.

Stream and allowlist buffers are allocated by the user as dma buffers
and mapped in virtual address space by the driver. The DMA and mapping
functions are linux specific. Hence create memory management and
allowlist linux structures. Add these linux memory structure pointers in
the tegra_hwpm parent structure.
