MLK-9971 Add XCBC-AES support for CAAM in i.MX6 family

Add XCBC-AES support to the CAAM crypto accelerator core in
the i.MX6 family of SoC devices.

Note that CAAM also goes by sec-4.0 or sec-5.0 in other product families (such as QorIQ).
Thus the property names are often tied to the sec-4.0+ nomenclature.
