crypto: caam - do not register AES-XTS mode on LP units

commit 83d2c9a9c17b1e9f23a3a0c24c03cd18e4b02520 upstream.

When using AES-XTS on a Wandboard, we receive a Mode error:
caam_jr 2102000.jr1: 20001311: CCB: desc idx 19: AES: Mode error.

According to the Security Reference Manual, the Low Power AES units
of the i.MX6 do not support the XTS mode. Therefore we must not
register XTS implementations in the Crypto API.
