phy: tegra: Select USB_PHY

I have hit the following build error:

	armv7a-hardfloat-linux-gnueabi-ld: drivers/phy/tegra/xusb.o: in function `tegra_xusb_port_unregister':
	xusb.c:(.text+0x2ac): undefined reference to `usb_remove_phy'
	armv7a-hardfloat-linux-gnueabi-ld: drivers/phy/tegra/xusb.o: in function `tegra_xusb_setup_ports':
	xusb.c:(.text+0xf30): undefined reference to `usb_add_phy_dev'

PHY_TEGRA_XUSB should select USB_PHY because it uses symbols defined in
the code enabled by that.
