crypto: talitos - Work around SEC6 ERRATA (AES-CTR mode data size error)
Talitos Security Engine AESU considers any input
data size that is not a multiple of 16 bytes to be an error.
This is not a problem in general, except for Counter mode
that is a stream cipher and can have an input of any size.
Test Manager for ctr(aes) fails on 4th test vector which has
a length of 499 while all previous vectors which have a 16 bytes
multiple length succeed.
As suggested by Freescale, round up the input data length to the
nearest 16 bytes.
