arm64: dts: ls1046a: mark crypto engine dma coherent
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:
> kernel BUG at drivers/crypto/caam/jr.c:247!
> Internal error: Oops - BUG: 0 [#1] PREEMPT SMP
