drivers: thermal: allow ti-soc-thermal run without pcb zone
This patch changes the behavior of TI SoC thermal driver when there is a PCB thermal zone. Instead of reporting an error code when reading from PCB temperature sensor fails, this patch will make the driver attempt to compose the hotspot extrapolation based on bandgap readings only.
