Subject: [PATCH net-next v4 12/19] net/mlx5e: Implement PSP operations .assoc_add and .assoc_del

From: Raed Salem <raeds@...dia.com>

Implement .assoc_add and .assoc_del PSP operations used in the tx control
path. Allocate the relevant hardware resources when a new key is registered
using .assoc_add. Destroy the key when .assoc_del is called. Use a atomic
counter to keep track of the current number of keys being used by the
device.

Notes:
    v4:
    - delete unused struct mlx5e_psp_sa_entry declaration
    - use psp_key_size() instead of pas->key_sz in mlx5e_psp_assoc_add()
    v1:
    - https://lore.kernel.org/netdev/20240510030435.120935-11-kuba@kernel.org/
