crypto: drbg - use single block cipher API The CTR DRBG only encrypts one single block at a time. Thus, use the single block crypto API to avoid additional overhead from the block chaining modes. With the patch, the speed of the DRBG increases between 30% and 40%. The DRBG still passes the CTR DRBG CAVS test.
