[PATCH 1/6] dt: bindings: net: add bindings for QCN6122

From: George Moussalem <[email protected]>

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
(Application Processor SubSystem), APSS will be unaware of such a decice
so 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 as
introduced by WCN6750. It has 5 CE and 8 DP rings.

QCN6122 is similar to WCN6750 and follows the same codepath as for
WCN6750.
