Unlike other ATH11K PCIe devices which are enumerated by APSS processor (Application Processor SubSystem), WCN6750 gets enumerated by the WPSS Q6 processor (Wireless Processor SubSystem); In simple terms, though WCN6750 is PCIe device, it is not attached to the APSS processor, APSS will not know of such a device being present in the system and therefore WCN6750 will be registered as a platform device to the kernel core like other supported AHB devices. WCN6750 needs both AHB and PCI APIs for it's operation, it uses AHB APIs for device probe/boot and PCI APIs for device setup and register accesses. Because of this nature, it is referred as a hybrid bus device. Refactor PCI code to support hybrid bus devices like WCN6750.
