crypto: powerpc/aes - aes tables

4K AES tables for big endian. To reduce the possiblity of
timing attacks, the size has been cut to 8KB + 256 bytes
in contrast to 16KB in the generic implementation. That
is not perfect but at least a good tradeoff for CPU limited
router devices.

/*
* These big endian AES encryption/decryption tables have been taken from
* crypto/aes_generic.c and are designed to be simply accessed by a combination
* of rlwimi/lwz instructions with a minimum of table registers (usually only
* one required). Thus they are aligned to 4K. The locality of rotated values
* is derived from the reduced offsets that are available in the SPE load
* instructions. E.g. evldw, evlwwsplat, ...
*
* For the safety-conscious it has to be noted that they might be vulnerable
* to cache timing attacks because of their size. Nevertheless in contrast to
* the generic tables they have been reduced from 16KB to 8KB + 256 bytes.
* This is a quite good tradeoff for low power devices (e.g. routers) without
* dedicated encryption hardware where we usually have no multiuser
* environment.
