How about using this approach instead?   It simplifies the kconfig
for the gadget drivers by providing a boolean "which hardware"
symbol, so gadget drivers don't need to make their own.  The symbol
that's synthetic is the one needed only by the Makefile.

It's a larger change, but likely a better one.  Greg, does it
behave for you?

Roman, this seems to trigger some kind of xconfig/menuconfig bug,
since I can go down the list of hardware options (net2280, goku,
dummy -- three, not the single one Adrian was working with) and
each deselects the previous selection ... but then it's impossible
to turn off the dummy, and select real hardware.
