Subject: [PATCH v2] lib: update the licence of the ASN.1 encoder and decoder

The open source project leancrypto (github.com/smuellerDD/leancrypto)
has asked to use the ASN.1 encoder/decoder files from the kernel.
Since leancrypto is licensed under BSD-3-Clause the fairest thing to do for everyone is add BSD-3-Clause as an OR to the SPDX tag so every project could import them under the same terms.

The copyright holders of both files have agreed to this change.
