PATCH 1/1 dt-bindings: bus: Convert cznic,moxtet to DT schema

Convert the cznic,moxtet binding to DT schema format. It's a straight-forward conversion.

+title: Turris Moxtet SPI bus

+description: >
+  Turris Mox module status and configuration bus (over SPI)
+
+  The driver finds the devices connected to the bus by itself, but it may be
+  needed to reference some of them from other parts of the device tree. In that
+  case the devices can be defined as subnodes of the moxtet node.
