[PATCH 1/5] public-keys: ecdsa: remove list in ecdsa keys

[Sascha Hauer <s.hauer@pengutronix.de>]

We have a function to iterate over ecdsa keys. This is unused and
shouldn't be necessary as we have a function to iterate over public
keys. Remove the iterator and the list entry which gives us the
possibility to put ecdsa keys into the RO data section.
