MIPS: JZ4740: Probe OHCI platform device via DT
The DT fragment will select the ohci-platform driver, since that can handle the JZ4740 OHCI just fine. While I don't have a JZ4740-based board with anything connected to the USB host controller, I did test the generic OHCI driver successfully on a JZ4770-based board. The device is disabled by default; boards that want to use it can override the "status" property. The mass-production Qi LB60 boards don't use the USB host controller.
