[PATCH 1/2] dt-bindings: w1: Add YAML DT Schema for AMD w1 master and MAINTAINERS entry

[Kris Chaplin]

Add YAML DT Schema for the AMD w1 master IP.

This hardware guarantees protocol timing for driving off-board devices such
as thermal sensors, proms, etc using the 1wire protocol.

Add MAINTAINERS entry for DT Schema.
