Add YAML DT schema for the AMD AXI w1 host IP. This hardware guarantees protocol timing for driving off-board devices such as thermal sensors, proms, etc using the 1wire protocol. The IP has a register to detect hardware version and so the binding does not have an explict version number. Add MAINTAINERS entry for DT schema.
