[PATCH] broadband-modem-mbim: disable CDMA capabilities until we actually support MBIM+CDMA

[Dan Williams]

CDMA-capable modems (like a Sierra EM7355) will fail to even enable,
because the internal CDMA code tries to initialize using AT commands and
that fails because many MBIM modems don't have an AT port.  We should
figure out how to support minimal MBIM + CDMA using MBIM instead of
AT-anything.
