caam/qi frontend (i.e. caamalg_qi) mustn't be used in case it runs on a
DPAA2 part (this could happen when using a multiplatform kernel).
Fixes: 297b9cebd2fc ("crypto: caam/jr - add support for DPAA2 parts")

If this patch won't make it into v4.14 (likely the case),
eventually it should be sent to -stable.
