From: Eduardo Valentin <eduardo.valentin@ti.com>
This patch changes a dtsi file to contain the thermal data
for MPU domain on OMAP4 and later SoCs. This data will
enable the passive cooling with CPUfreq cooling device
at 100C and the system will do a thermal shutdown at 125C.
This thermal data can be reused across TI SoC devices.

From: Eduardo Valentin <eduardo.valentin@ti.com>
OMAP4460 devices can reach high temperatures and thus
needs to have cpufreq-cooling on systems running on it.
This patch adds the required cooling device properties
so that cpufreq-cpu0 driver loads the cooling device.
