BeagleBoard-X15 has capability for a fan and has an onboard TMP102
temperature sensor as well. This allows us to create a new thermal
zone (called, un-imaginatively "board"), and allows us to use some
active cooling as temperatures start edge upward in the system by
creating a new alert temperature (emperically 50C) for cpu.
NOTE: Fan is NOT mounted by default on the platform, in such a case,
all we end up doing is switch on a regulator and leak very minimal
current.

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.
