[PATCH V2 2/2] ARM: dts: bcm283x: Add CPU thermal zone with 1 trip point

[Stefan Wahren <stefan.wahren@i2se.com>]

As suggested by Eduardo Valentin this adds the thermal zone for
the bcm2835 SoC with its single thermal sensor. We start with
the criticial trip point and leave the cooling devices empty
since we don't have any at the moment.

Changes in V2:
- add missing thermal-sensor-cells property
- change gpu-thermal to cpu-thermal
