Add arch_init() and arch_deinit() ops to the PCI and AHB family ops to support allocation and cleanup of architecture-specific fields in ath12k_base. Define shared ath12k_wifi7_arch_init() and ath12k_wifi7_arch_deinit() functions to handle DP device allocation and cleanup for Wi-Fi 7 across both PCI and AHB. Introduce a new header file wifi7/core.h to declare functions defined in wifi7/core.c. Currently, DP device allocation and cleanup are handled via arch_init() and arch_deinit(), which can be extended to support additional architecture-specific initialization in the future. Define common ath12k_wifi7_arch_init() and ath12k_wifi7_arch_deinit() functions to handle allocation and cleanup for Wi-Fi 7. Add a new header file wifi7/core.h to declare common Wi-Fi 7 functions. Add ath12k_wifi7_dp_device_alloc() and ath12k_wifi7_dp_device_free() to handle allocation and deallocation of the DP device object for Wi-Fi 7. Add ath12k_dp_cmn_device_init() and ath12k_dp_cmn_device_deinit() to initialize and deinitialize common DP device fields. Introduce a new header file dp_cmn.h to declare these functions, which can also be used to expose new common DP functions that need to be invoked from non-DP code. Rename existing DP allocation and cleanup functions to ath12k_dp_setup() and ath12k_dp_cleanup() to better reflect their purpose in the updated design. Replicate device-related fields such as device and hw_params in the DP device object to align with the new design, which limits per packet data path object usage to DP specific objects.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
