MIPS: Loongson: Fix boot warning about hwmon_device_register()

Replace hwmon_device_register() with hwmon_device_register_with_info()
to fix the following boot warning :

[ 9.029924] Loongson Hwmon Enter...
[ 9.106850] (NULL device *): hwmon_device_register() is deprecated. Please convert the driver to use hwmon_device_register_with_info().
