[PATCH v4 2/3] dt-bindings: nvmem: mediatek: document deprecated efuse property

[Allen-KH Cheng]

From: Allen-kh Cheng <allen-kh.cheng at mediatek.corp-partner.google.com>

We mark mediatek,mt8173-efuse and mediatek,efuse as deprecated to
prevent them from being the single compatible in the future.

The mediatek,efuse compatible should be used as generic fallback for
all MediaTek chipsets.
