V3 changes:
* change clock name from 'g3d' to 'core'
* disable node by default in exynos5250.dtsi
* move dt-bindings before node addition in device tree
V2 changes:
* move mali node as /soc sub-node
* move gpu_opp_table as mali sub-node
* minor style updates
* test on arndale board
* enable by default
* add dt bindings, in a separate patch
