Krzysztof Kozlowski bbb4c17939 dt-bindings: thermal: simplify few bindings
Simplify few bindings which already reference thermal-sensor.yaml schema
by dropping unneeded requiring of '#thermal-sensor-cells' and dropping
assigned-clocks properties (core schema allows it if 'clocks' are
there).

description: |
TSENSOR provides thermal and voltage sensors which monitor temperature
and voltage of the chip. Sensors are placed across the die to gauge the
temperature of the whole chip. The TSENSOR module:
Generates an interrupt to SW to lower temperature via DVFS on reaching
a certain thermal/voltage threshold.
Generates a signal to the CAR to reduce CPU frequency by half on reaching
a certain thermal/voltage threshold.
Generates a signal to the PMC when the temperature reaches dangerously high
levels to reset the chip and sets a flag in the PMC.
TSENSOR has two channels which monitor two different spots of the SoC.
