[Buildroot] [git commit] boot/arm-trusted-firmware: add target board options

[Arnout Vandecappelle (Essensium/Mind)]

commit: https://git.buildroot.net/buildroot/commit/?id=6103d9b5971c61c897ea43e11ee8559c0df04832
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Some platforms such as TI's k3 outputs a TARGET_BOARD directory
in their ATF build output paths after PLATFORM.
$(@D)/build/<PLATFORM>/ does not contain the debug or release
directories for these platforms.
They are under $(@D)/build/<PLATFORM>/<TARGET_BOARD>/
