imx: mx6: add display of CPU temperature grade in print_cpuinfo()
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: Industrial temperature grade (-40C to 105C) at 42C
CPU: Extended Commercial temperature grade (-20C to 105C) at 42C
