dt-bindings: usb: Convert multiple "usb-ohci" bindings to DT schema

"usb-ohci" is another "generic" OHCI controller compatible string used by
several platforms. Add it to the generic-ohci.yaml schema and remove all
the old binding docs.

Marvell pxa-usb.txt has "usb-ohci" in the example, but actual users don't,
so drop it.
