Florian, does SF2 or b53 have a temperature sensor?
John, does the qca8k have a temperature sensor?

If we do have a switch with a temperature sensor, making the HWMON
code available as a library for switch drivers to use makes sense.
However, if we move the Marvell code into the PHY driver, and there
are no other switches with temperature sensors, we should just remove
it.
