drivers/thermal/rcar_gen3_thermal: Improve logging during probe

When setting up a new board, a plain "Can't register thermal zone"
didn't help me much because the thermal zones in DT were all fine. I
just had a sensor entry too much in the parent TSC node. Reword the
failure/success messages to contain the sensor number to make it easier
to understand which sensor is affected. Example output now:

rcar_gen3_thermal e6198000.thermal: Sensor 0: Loaded 1 trip points
rcar_gen3_thermal e6198000.thermal: Sensor 1: Loaded 1 trip points
rcar_gen3_thermal e6198000.thermal: Sensor 2: Loaded 1 trip points
rcar_gen3_thermal e6198000.thermal: Sensor 3: Can't register thermal zone
