Add PowerVR Series5 SGX GPUs for the TI SoCs

Browse Source 
With the Imagination Rogue GPU binding added, let's also add the devicetree
 binding for earlier SGX GPUs. Let's also patch the TI SoCs for the related
 SGX GPU nodes.
 
 Based on the mailing list discussions, the conclusion was that we need two
 separate device tree bindings, one for Rogue and upcoming GPUS, and one for
 the older SGX GPUs.
 
 For merging the changes, I applied the binding changes together with the
 TI SoC related changes into a branch leaving out the sun6i and mips changes
 as suggested by Rob.
 
 These changes are mostly 32-bit SoCs, but also contains one arm64 change.
 It does not cause any merge conflicts.
