When CONFIG_IMX6_THERMAL is defined print the CPU temperature grade info along with the current temperature.
Before: CPU: Temperature 42 C
After: CPU: Automotive temperature grade (-40C to 125C) at 42C CPU: Industiral temperature grade (-40C to 105C) at 42C CPU: Extended Commercial temperature grade (-20C to 105C) at 42C

v2:
- moved display of CPU temperature grade to own patch and combined with the current temperature from the thermal sensor driver
- add example output to description
