[PATCH] ARM: dts: Fix undocumented LM75 compatible nodes

["Rob Herring (Arm)" <robh@kernel.org>]

"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. NXP makes a LM75A and LM75B.
Both are 11-bit resolution and 100ms sample time, so "national,lm75b" is
the closest match.

While we're here, fix the node names to use the generic name
"temperature-sensor".
