Following this discussion, Gustavo never sent any patch to fix
arm_juno_defconfig, and the ATF build broken was still broken as of
today. So I went ahead, and bumped the ATF version to 1.3, to at least
fix the build issue.

It would be nice if you could give it a test on the actual hardware,
and perhaps bump ATF to an ever newer version.
