Though it is a PCIe device, since it is not attached to APSS processor (Application Processor SubSystem), APSS will be unaware of such a decice and hence it is registered to the APSS processor as a platform device(AHB). Because of this hybrid nature, it is called as a hybrid bus device. A new variable is defined in bus params to indicate the hybrid nature. Add bus params for WCN6750.
