ARM: dts: Fix undocumented LM75 compatible nodes
"lm75" without any vendor is undocumented. It works with the Linux kernel since the I2C subsystem will do matches of the compatible string without a vendor prefix to the i2c_device_id and/or driver name. Mostly replace "lm75" with "national,lm75" as that's the original part vendor and the compatible which matches what "lm75" matched with. In a couple of cases the node name or compatible gives a clue to the actual part and vendor and a more specific compatible can be used. In these cases, it does change the variant the kernel picks. "nct75" is an OnSemi part which is compatible with TI TMP75C based on a comparison of the OnSemi NCT75 datasheet and configuration the Linux driver uses. Adding an OnSemi compatible would be an ABI change. "nxp,lm75" is most likely an NXP part. Alexander Stein says the i.MX53 boards are a NXP LM75A as well. NXP makes a LM75A and LM75B. Both are 11-bit resolution and 100ms sample time. The "national,lm75a" is 9-bit, so "national,lm75b" is the closest match for both NXP variants. While we're here, fix the node names to use the generic name "temperature-sensor".
