usb: Do not compile USB_STORAGE with BLK && !DM_USB
The USB storage driver does not compile when CONFIG_BLK is set, but DM_USB is not set, as we're missing the DM device links for CONFIG_BLK enabled code paths. So far it looks like nobody fell into this trap, because no board enabled CONFIG_BLK and CONFIG_USB_STORAGE while not enabling CONFIG_DM_USB, but we should still reflect that dependency properly in Kconfig so that implicit enabling of CONFIG_USB_STORAGE works.
