crypto: provide single place for hash algo information
This patch provides a single place for information about hash algorithms, such as hash sizes and kernel driver names, which will be used by IMA and the public key code. Changelog: - Fix sparse and checkpatch warnings - Move hash algo enums to uapi for userspace signing functions.
