[PATCH] dt-bindings: usb: ux500: Convert to DT schema

[Linus Walleij]

Convert the Ux500 MUSB text binding to DT schema. Describe the APB
clock and the existing ordered DMA endpoint channels, and reference
the common dual-role USB properties.

Convert the Ux500 MUSB text binding to DT schema, describing the APB
clock, ordered DMA endpoint channels and common dual-role USB properties.

This patch is split from the Ux500 DeviceTree validation cleanup series.

Prepared with Codex.
