[Buildroot] [git commit branch/2019.05.x] boot/arm-trusted-firmware: licensing info is only valid for v1.4

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=376c8446eb5605432bb6929d7a4677d9649bddc2
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.05.x

The licensing information, and especially the name of the license file,
is known only for the official v1.4 version. For example, in later
versions, the license file has been renamed.

Since we can't be sure of the licensing information for custom versions,
or for versions from git, define that only for the known v1.4 version.
