[PATCH] arm64: dts: Add Adreno GPU and GPU smmu definitions

[Jordan Crouse <jcrouse-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>]

Add an initial node for the Adreno GPU and it's companion
SMMU. The GPU node is mostly complete except for a bare
bones power table that will be filled out more completely
later.
