Add QCN6122 platform support.
QCN6122 is a PCIe based solution that is attached to and enumerated
by the WPSS (Wireless Processor SubSystem) Q6 processor.
Though it is a PCIe device, since it is not attached to APSS processor,
APSS will be unaware of such a decice and hence it is registered to the
APSS processor as a platform AHB device.
As such, QCN6122 is a hybrid bus type device and follows the same
codepath as for WCN6750.
This is a heavily simplified version of below downstream patch:
