[PATCH v2 4/4] wifi: ath12k: enforce CPU-endian format for all QMI messages

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

Due to internal endianness handling within the QMI subsystem, all QMI
requests and responses must now be provided in CPU byte order. Replace all
QMI-related data types with CPU-endian types and add the necessary
conversions to ensure correct interpretation across architectures.

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