Subject: crypto: arm/aes-ce - fix for big endian

From: Ard Biesheuvel <[email protected]>

commit 58010fa6f71c9577922b22e46014b95a4ec80fa0 upstream.

The AES key schedule generation is mostly endian agnostic, with the exception of the rotation and the incorporation of the round constant at the start of each round. So implement a big endian specific version of that part to make the whole routine big endian compatible.
