[PATCH 15/28] crypto: omap-des: fix crypto engine initialization order

[Tero Kristo]

The crypto engine must be initialized before registering algorithms,
otherwise the test manager will crash as it attempts to execute
tests for the algos while they are being registered.

Fixes: f1b77aaca85a ("crypto: omap-des - Integrate with the crypto engine framework")
