econet: Clean up kernel config and move subtarget devices into own file

The kernel config accidentally contains CONFIG_UBIFS_FS_AUTHENTICATION
which select a number of other unnecessary components, remove them.

The target has at least two subtargets, only one is currently
implemented. Move the Device builds into a file for this subtarget.
