[PATCH ath-next v2 07/17] wifi: ath12k: Add hybrid_bus_type in ath12k_hw_params

[Aaradhana Sahu]

QCN6432 is a PCIe-based device attached to the WCSS Q6 processor,
but it is registered as a platform (AHB) device. It uses AHB APIs
for probe and boot. Because of this hybrid nature, it is called as
a hybrid bus device.

Introduce a hybrid_bus_type field in ath12k_hw_params to indicate the
hybrid nature of the device.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.6-01243-QCAHKSWPL_SILICONZ-1
Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.6-01322-QCAHKSWPL_SILICONZ-1
Tested-on: QCN6432 hw1.0 AHB WLAN.WBE.1.6-01322-QCAHKSWPL_SILICONZ-1
