[PATCH] crypto: Add SPDX ids to some files

[Tim Bird]

Add SDPX-License-Identifier ID lines to assorted C files in the
crypto directory, that are missing them.  Remove licensing text,
except in cases where the text itself says that the notice must
be retained.

Signed-off-by: Tim Bird <tim.bird@xxxxxxxx>

---
Note that this does not finish adding SPDX id lines to all the
files, as there are a few special cases with weird license texts.
