Enable smack, ramdisk and nbd in linux-staging-ti kernel

This changeset enables the necessary features for AGL in the linux-ti-staging kernel
by using configuration fragments. These are additive to the configuration matrix
done by linux-ti-staging itself (per board).
Apply likewise for other needed options.
