defconfig: arm64: msm: Add defconfigs needed for data calls

Add the DUMMY network interface and the crypto ECHAINIV module
needed for tunneling in advanced data call scenarios.

ECHAINIV is the default algorithm for CBC which is needed for
setting up a tunnel using XFRM state. Dummy network device is used
to route the IPv6 tunneled traffic when there is no IPv6 route
present on a wireless device. The default route in the dummy
interface routing table will route egress packets.
