[PATCH 07/12] usb: gadget: at91_udc: Document DT clocks and clock-names property

[Alexandre Belloni]

From: Boris Brezillon <boris.brezillon@xxxxxxxxxxxxxxxxxx>

The at91_udc driver request 2 clocks, and thus need them to be defined in
the device tree.
Document the clocks and clock-names properties so that everybody use the
correct names.
