[PATCH 06/11] wifi: ath12k: fix endianness handling in QMI firmware capabilities

[Alexander Wilhelm <alexander.wilhelm@westermo.com>]

Ensure proper endianness support for big-endian platforms by correcting
data types in the QMI firmware capabilities response message and its
associated structures as well. Add missing byte swaps wherever these
structures are accessed or modified.

Fixes: d889913205cf ("wifi: ath12k: driver for Qualcomm Wi-Fi 7 devices")
