[PATCH] arm/xen: Point the comment at the YAML binding

The binding was converted by commit 4dbfe5467485 ("dt-bindings: arm:
xen: Convert to DT schema"), so Documentation/devicetree/bindings/arm/
xen.txt no longer exists.

Point the comment at the YAML schema.

Fixes: 4dbfe5467485 ("dt-bindings: arm: xen: Convert to DT schema")
