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
