Yes, it is odd, but then again, so is typec :(

I think this is an artifact of the code living in two different
directories for a while (drivers/staging/ and drivers/usb) and now
coming together.

Guenter, can you make up a patch to fix up the Kconfig entries in
drivers/usb/typec/Kconfig to make a bit more sense now that things are
all living in the same place in the tree?
