2dd652e665 doc: imx: habv4: Remove secure_boot.txt guide
The secure_boot.txt guide was replaced by mx6_mx7_secure_boot.txt and
mx6_mx7_spl_secure_boot.txt documents.

Both documents covers all steps needed for SPL and non-SPL tagets,
so remove secure_boot.txt file to avoid duplicated content.

8a23fc9c94 doc: imx: habv4: Remove extra hab directory for a cleaner documentation structure
There is no need to have an extra hab directory under doc/imx/.

cleaner documentation structure.
