Find hwmon path based on input path type

If the input path starts with /devices, find the hwmon path
using the findHwmonFromDevPath function, otherwise use
findHwmonFromOFPath.

Also change the argument name to something more generic.

Did not change the argument's short name so the service
file isn't coupled to this change.

Tested: Tested with both paths.
