[PATCH 1/3] dt-bindings: gpu: mali-utgard: add rockchip,rk3328-mali compatible

[Heiko Stuebner]

The rk3328 quad-core Cortex A53 uses a Mali-450MP2 with 2 PPs, so
add a compatible for it.

For the series,

Reviewed-by: Rob Herring <robh-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>

Though I don't think it's really necessary to enable the gpu per board 
as it has no pinout. Default enabled would be better IMO.
