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.
