crypto: talitos - Simplify per-channel initialization
There were multiple loops in a row, for each separate step of the initialization of the channels. Simplify to a single loop. Signed-off-by: Martin Hicks <mort@bork.org> Acked-by: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
