[PATCH v2 2/2] dt-bindings: net: adin: Document bindings for fast link down disable

[Ken Sloat]

The ADI PHY contains a feature commonly known as "Fast Link Down" and
called "Enhanced Link Detection" by ADI. This feature is enabled by
default and provides earlier detection of link loss in certain
situations.

Document the new optional flags "adi,disable-fast-down-1000base-t" and
"adi,disable-fast-down-100base-tx" which disable the "Fast Link Down"
feature in the ADI PHY.
