[PATCH] Kconfig/ehci/zynq: Add ULPI dependency

[Olliver Schinagl]

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'
