doc: mxc_hab: Move HAB related info to the appropriate doc
Currently the High Assurance Boot procedure is documented in two
places:
- doc/README.imx6
- doc/README.mxc_hab
It is better to consolidate all HAB related information into
README.mxc_hab file, so move the content from README.imx6 to
README.mxc_hab.
