Define the structure of ath12k_dp_peer and also define APIs for creation and deletion of ath12k_dp_peer based on STA state, as the ath12k_dp_peer is intended to be used in the subsequent set of patches. Maintain ath12k_dp_peer in a linked list in ath12k_dp_hw (which is a datapath component of ath12k_hw) and protect this list using spinlock "peer_lock". Store peer id based table (array of RCU pointers) of ath12k_dp_peer in ath12k_dp_hw. Use this peer id table to refer in the per packet Tx and Rx paths as it provides faster access to ath12k_dp_peer in comparison to linked list iterative search using peer id or mac address. Add support to handle deletion of ath12k_dp_peer in case of core reset. This patch is adding and deleting ath12k_dp_peer created for MLO STA to the above mentioned RCU pointer table. Addition and deletion of ath12k_dp_peer for non-MLO STA to RCU pointer table is handled in the subsequent following patch. Structure ath12k_ml_peer is created and deleted for MLO peers at the time of connect and disconnect and there is no other use case of it. With the above design in place for ath12k_dp_peer, ath12k_ml_peer becomes redundant. Hence, remove the structure ath12k_ml_peer and the list "ml_peers" present in ath12k_hw maintaining linked list of ath12k_ml_peer.

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.
