usb: fotg210: Fix Kconfig for USB host modules
The kernel robot reports a link failure when activating the FOTG210 host subdriver with =y on a system where the USB host core is a module (CONFIG_USB=m). This is a bit of special case, so mimic the Kconfig incantations from DWC3: let the subdrivers for host or peripheral depend on the host or gadget support being =y or the same as the FOTG210 core itself. This should ensure that either: - The host (CONFIG_USB) or gadget (CONFIG_GADGET) is compiled in and then the FOTG210 can be either module or compiled in. - The host or gadget is modular, and then the FOTG210 module must be a module too, or we cannot resolve the symbols at link time.
