[PATCH net-next v2 1/2] dt-bindings: net: adin: add property for link-status pin polarity

[Josua Mayer]

ADIN1200/1300 support software control over LINK_ST pin polarity.
This is a fixed function output reflecting phy link-status that is not
otherwise controllable by software.

Add new property adi,link-st-polarity for specifying polarity as either
active-high (reset-default) or active-low.
