[PATCH 12/24] staging: ccree: fix cipher naming convention

From: Gilad Ben-Yossef
Date: Tue Dec 12 2017 - 09:55:15 EST

The blkcipher files were using a func naming convention which was
inconsistent (ssi vs. cc), included a long prefix (ssi_ablkcipher)
and often too long.

Make the code more readable by switching to a simpler, consistent naming
convention.
