hwmon: (sch5627) Convert to hwmon_device_register_with_info()
hwmon_device_register() is deprecated. Convert driver to use hwmon_device_register_with_info() and remove sysfs attributes which are now being handled by the hwmon subsystem. Channel handling was inspired by corsair-cpro. Tested on a Fujitsu Esprimo P720.
