Cannot initialize renesas yocto build environment

The current way that 3rd party HW integrations (such as Renesas) are done for Boot2Qt yocto environment, no longer works. A fix was made to the Google's repo tools that now prevent the initialization using the manifest.xml from the meta repo itself.

repo init -u git://code.qt.io/yocto/meta-boot2qt-renesas -m conf/manifest.xml -b warrior
...
error.ManifestInvalidPathError: <linkfile> invalid "dest": .repo/local_manifests/boot2qt.xml: bad component: .repo 

The workaround is to use a separate manifest repository, which is the proper way of using the repo tool.

repo init -u git://code.qt.io/yocto/boot2qt-manifest -b renesas -m warrior.xml 

This will need to be addressed in the documentations.
