Guenter Roeck bfdd34f1ca hw/arm: ast2400/ast2500: Wire up EHCI controllers 
Initialize EHCI controllers on AST2400 and AST2500 using the existing
TYPE_PLATFORM_EHCI. After this change, booting ast2500-evb into Linux
successfully instantiates a USB interface.

ehci-platform 1e6a3000.usb: EHCI Host Controller
ehci-platform 1e6a3000.usb: new USB bus registered, assigned bus number 1
ehci-platform 1e6a3000.usb: irq 21, io mem 0x1e6a3000
ehci-platform 1e6a3000.usb: USB 2.0 started, EHCI 1.00
usb usb1: New USB device found, idVendor=1d6b, idProduct=0002, bcdDevice= 5.05
usb usb1: New USB device strings: Mfr=3, Product=2, SerialNumber=1
usb usb1: Product: EHCI Host Controller
