[Buildroot] [PATCHv2] boot/atf: licensing info is only valid for v1.4

[Yann E. MORIN]

The licensing information, and expecially 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.

Changes v1 -> v2:
  - adopted by Yann from Adam
  - don't change the filename, but move the licensing info
