This patch adds i.MX7 thermal sensor support, most of the i.MX7 thermal sensor functions are same with i.MX6 except the registers offset/layout, so we move those registers offset/layout definitions to soc data structure. i.MX7 uses single calibration data @25C, the calibration data is located at OCOTP offset 0x4F0, bit[17:9], the formula is as below: Tmeas = (Nmeas - n1) + 25; n1 is the fuse value for 25C.
