commit ba8da03fa7dff59d9400250aebd38f94cde3cb0f upstream.

Crypto engine (CAAM) on LS1012A platform is configured HW-coherent,
mark accordingly the DT node.

Lack of "dma-coherent" property for an IP that is configured HW-coherent
can lead to problems, similar to what has been reported for LS1046A.
