Subject: [PATCH] ARM: dts: Makefile: build arm64 device tree

From: Peng Fan <peng.fan@....com>

To support aarch32 mode linux on aarch64 hardware, we need
build the device tree, so include the arm64 device tree path.

V1:
 This is just the device tree part. Besides this,
 I am not sure whether need to create a standalone defconfig under arm32
 for aarch32 mode linux on aarch64 hardware, or use multi_v7_defconfig.
 multi_v7_defconfig should be ok, need to include LPAE config.
