Horia Geantă 004c19a34f arm64: dts: ls1046a: mark crypto engine dma coherent 
commit 9c3a16f88385e671b63a0de7b82b85e604a80f42 upstream.

Crypto engine (CAAM) on LS1046A platform is configured HW-coherent,
mark accordingly the DT node.

As reported by Greg and Sascha, and explained by Robin, lack of
"dma-coherent" property for an IP that is configured HW-coherent
can lead to problems, e.g. on v5.11:
