arm/crypto: Add optimized AES and SHA1 routines
Add assembler versions of AES and SHA1 for ARM platforms. This has provided up to a 50% improvement in IPsec/TCP throughout for tunnels using AES128/SHA1.

+ AES cipher algorithms (FIPS-197). AES uses the Rijndael
+ algorithm.
+
+ Rijndael appears to be consistently a very good performer in
+ both hardware and software across a wide range of computing
+ environments regardless of its use in feedback or non-feedback
+ modes. Its key setup time is excellent, and its key agility is
+ good. Rijndael's very low memory requirements make it very well
+ suited for restricted-space environments, in which it also
+ demonstrates excellent performance. Rijndael's operations are
+ among the easiest to defend against power and timing attacks.
+
+ The AES specifies three key sizes: 128, 192 and 256 bits
