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
