Add device tree node for Mali GPU for Exynos 542x SoC.
GPU is disabled by default, and is enabled for each board after the regulator
is defined. Tested on Odroid-XU4.

Changes since v2:
- separate patch for bindings
- fixed bindings typo

Changes since v1:
- used generic node and label for GPU
- added bindings for compatible
- fixed irq indentation
- fixed interrupt-names to match bindings
- added cooling cells for future TMU connection
- used generic node and label for GPU opp table
- removed always-on from SoC GPU regulator
