arm: mvebu: Implement secure boot

The patch implements secure booting for the mvebu architecture.

This includes:
- The addition of secure headers and all needed signatures and keys in
  mkimage
- Commands capable of writing the board's efuses to both write the
  needed cryptographic data and enable the secure booting mechanism
- The creation of convenience text files containing the necessary
  commands to write the efuses

The KAK and CSK keys are expected to reside in the files kwb_kak.key and
kwb_csk.key (OpenSSL 2048 bit private keys) in the top-level directory.
