QCN9575 is a Wi-Fi 8 target with a distinct hardware family that cannot
share the Wi-Fi 7 module. Add a dedicated wifi8/ subdirectory to host
QCN9575-specific code. Introduce Wi-Fi 8 build rules, base module source
files (wifi8/core.c, wifi8/pci.c, wifi8/pci.h), and add
ATH12K_DEVICE_FAMILY_WIFI8 to ath12k_device_family. Keep Wi-Fi 8 PCI
init/exit as stubs so the module builds cleanly and remains bisect-safe;
actual PCI driver registration and hardware support come in follow-up
patches.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.6-01243-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c7-00108-QCAHMTSWPL_V1.0_V2.0_SILICONZ_UPSTREAM-3
