[PATCH 6/7] dt-bindings: net: bluetooth: amlogic,w155s2-bt: add amlogic,shared-antenna

[christian . koever-draxl]

From: Christian Stefan Kövér-Draxl <ckoever@xxxxxxxxxx>

Some boards wire Bluetooth and Wi-Fi of the combo chip to a single
antenna. The Bluetooth RF has to be configured for that, which the
driver currently only does for the W265S2-class coexistence parts.
Add a property for boards to describe it.
