Wrap AES 192 and 256 info structures in !AES_ONLY_128_BIT_KEY_LENGTH 
This reduces the code size by not compiling in unnecessary info structures
when using only 128 bit AES.

Piotr Nowicki e048b91d25 Add returning a FAULT_DETECTED error on suspected FI attacks 
The change applies to the places where we prevent double synchronous
FI attacks with random delay, and where we do not respond to their
detection. The response to such an attack should be to return the
appropriate error code.
