[PATCH v3 11/15] crypto: public-keys: use array of public_keys

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

Instead of collecting the public keys directly in a section, we used to
collect pointers to the public keys. This indirection is unnecessary,
so drop it and put the keys directly into a section.
