meta-ibm: Add license information

When meta-ibm was split out as a subtree from openbmc the license
information was not copied to the new repository.

License of the metadata and code remains unchanged - this is only a
documentation update.

Fixes: 194ff4f1f5d44b12e9cb06ddafa6adb20174a13c
(From meta-ibm rev: 1bcd2f64f4fedd9a405db01160ef24d9a475e96d)
