e36ce99ee0 hwmon: (ds620) Fix overflows seen when writing temperature limits 
Module test reports:

temp1_max: Suspected overflow: [160000 vs. 0]
temp1_min: Suspected overflow: [160000 vs. 0]

This is seen because the values passed when writing temperature limits
are unbound.

f0967eea80 hwmon: convert drivers/hwmon/* to use module_i2c_driver() 
This patch converts the drivers in drivers/hwmon/* to use the
module_i2c_driver() macro which makes the code smaller and a bit simpler.
