Changes in v5:
-Don't modify the copyright of cpu.c file

Changes in v4:
-Added imx6 thermal sensor as a driver
-Renamed the config define to be more meaningful
-Move the clock code to clock.c
-Reusing ocotp driver for reading fuse
-Fix check for calibration fuse not programmed
-Aligned the slope computation with kernel
-Added Anadig register defines as seperate commit

Changes in v3:
-adds the mx6 temperature support
-adds the mx6 temperature support to mx6sabresd board.

Changes in v2:
-run checkpatch and fix reported issues
