phy: marvell: phy-mvebu-cp11i-utmi needs USB_COMMON

When USB and USB_COMMON are not enabled, phy-mvebu-cp110-utmi
suffers a build error due to a missing interface that is provided
by CONFIG_USB_COMMON, so make the driver depend on USB_COMMON.

ld: drivers/phy/marvell/phy-mvebu-cp110-utmi.o: in function `mvebu_cp110_utmi_phy_probe':
phy-mvebu-cp110-utmi.c:(.text+0x152): undefined reference to `of_usb_get_dr_mode_by_phy'
