dt-validate throws a few warnings when checking the aarch64 virt DTB.
Ensure that the virt DTB conforms to devicetree schema.

Some schema changes were needed, and should be in next Linux version [1]

I'm testing by running various virt machine configurations with -M
dumpdtb=qemu.dtb, then running dt-validate [1] and dtc:

  dt-validate -s linux/Documentation/devicetree/bindings/ qemu.dtb
  dtc -O dts qemu.dtb -o qemu.dts
