hwmon: (iio_hwmon) Allow the driver to accept hypen in device tree node names
Currently the driver calls hwmon_device_register_with_groups which does not accept hypen in node name and returns EINVAL. Use of hypen in device tree node name results in probe failure., however use of hypen in device tree node name is perfectly acceptable. Change this by allocating a duplicate managed string, replacing hypen with underscore and then calling hwmon_device_register_with_groups. This allows the use of hypen in device tree node name while maintaining backwards compatibility and preventing any possible regressions with user space.
