[U-Boot] [PATCH 3/3] nitrogen6x: add secure boot support

[Gary Bisson]

Selecting the proper options to enable the build of the HAB tools.

Also adding a CSF section to the imx final image so it can contain
the signature information.

Note, this support is disabled by default, one will have to select
the SECURE_BOOT configuration through menuconfig to enable it.
