Subject: [PATCH 4.9 20/53] arm64: dts: ls1043a: mark crypto engine dma coherent

From: Horia Geantă <horia.geanta@....com>

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.

Cc: <stable@...r.kernel.org> # v4.8+
Fixes: 63dac35b58f4 ("arm64: dts: ls1043a: add crypto node")
