crypto: talitos - Fix ctr(aes) on SEC1

While ctr(aes) requires the use of a special descriptor on SEC2 (see
commit 70d355ccea89 ("crypto: talitos - fix ctr-aes-talitos")), that
special descriptor doesn't work on SEC1, see commit e738c5f15562
("powerpc/8xx: Add DT node for using the SEC engine of the MPC885").

However, the common nonsnoop descriptor works properly on SEC1 for
ctr(aes).

Add a second template for ctr(aes) that will be registered
only on SEC1.
