The crypto API's support for alignmasks for ahash algorithms is nearly
useless, as its only effect is to cause the API to align the key and
result buffers.  The drivers that happen to be specifying an alignmask
for ahash rarely actually need it.  When they do, it's easily fixable,
especially considering that these buffers cannot be used for DMA.

In preparation for removing alignmask support from ahash, this patch
makes the s5p-sss driver no longer use it.  This driver didn't actually
rely on it; it only writes to the result buffer in
s5p_hash_copy_result(), simply using memcpy().  And this driver only
supports unkeyed hash algorithms, so the key buffer need not be
considered.
