Remove:

- CONFIG_CBFS
- anything that's conditional on CONFIG_CBFS == 0
- files that were only included for CONFIG_CBFS == 0
In particular:
- elfboot
- stream boot code
- mini-filo and filesystems (depends on stream boot code)

After this commit, there is no way to build an image that is not using
CBFS anymore.
