The ZYNQ has an ULPI interface to a USB PHY and thus depends on it. Prevents the following compilation problem.
drivers/usb/host/built-in.o: In function `ehci_zynq_probe': drivers/usb/host/ehci-zynq.c:53: undefined reference to `ulpi_init' drivers/usb/host/ehci-zynq.c:60: undefined reference to `ulpi_write' drivers/usb/host/ehci-zynq.c:63: undefined reference to `ulpi_write' drivers/usb/host/ehci-zynq.c:66: undefined reference to `ulpi_write' drivers/usb/host/ehci-zynq.c:69: undefined reference to `ulpi_write'
