Subject: [PATCH 4/9] arm64: dts: ls1046a: add missing dma ranges property

From: Laurentiu Tudor <laurentiu.tudor@....com>

ls1046a has a 48-bit address size so make sure that the dma-ranges
reflects this. Otherwise the linux kernel's dma sub-system will set the
default dma masks to full 64-bit, badly breaking dmas.
