[PATCHv4 15/18] arm: dts: add omap5 GPU thermal data

[Eduardo Valentin <eduardo.valentin@ti.com>]

This patch changes a dtsi file to contain the thermal data
for GPU domain on OMAP5 and later SoCs. This data will
enable a thermal shutdown at 125C.

This thermal data can be reused across TI SoC devices.
