[PATCH 3.16 183/305] crypto: ux500 - memmove the right size

[Ben Hutchings]

3.16.37-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Linus Walleij <linus.walleij@xxxxxxxxxx>

commit 19ced623db2fe91604d69f7d86b03144c5107739 upstream.

The hash buffer is really HASH_BLOCK_SIZE bytes, someone
must have thought that memmove takes n*u32 words by mistake.
Tests work as good/bad as before after this patch.
