Subject: [PATCH 2/2] arm64: dts: ls2080a: fsl-mc dt node updates

From: Stuart Yoder <stuart.yoder@....com>

updates to the fsl-mc node for full functionality:
   -msi-parent is needed for interrupt support
   -ranges is needed to enable the bus driver to translate bus addresses
   -dpmac nodes provide a basis for relating dpmac objects to PHYs
