[PATCH v2 3/4] LICENSES: exceptions: factor out eCos-exception-2.0 for GPL

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

We have code imported from eCos that's licensed with this exception.
Replace instances of the exceptions with a SPDX-License-Identifier
referencing the exception in our LICENSES directory.
