arm64: dts: ls1043a: mark crypto engine dma coherent

commit 4fb3a074755b7737c4081cffe0ccfa08c2f2d29d upstream.

Crypto engine (CAAM) on LS1043A 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.
