This logic sets interface_modes to be the modes that are supported on
every radio (starts with all modes supported and then masks off the ones
that are not supported on a given radio). That means that if radio 0
supports a mode that radio 1 does not support, then we don't advertise
support for that mode. Just want to verify that is the correct logic,
and that instead we don't want to start with no modes supported and then
OR in the ones that are supported so that we get the list of modes that
are supported on ANY radio instead of ALL radios.

note that in the example I mentioned above, this logic could say a given
mode is enabled even though the bit isn't set in the interface_modes
listed above
