hwmon: (corsair-psu) Fix probe when built-in
It seems that when the driver is built-in, the HID bus is
initialized after the driver is loaded, which whould cause
module_hid_driver() to fail.
Fix this by registering the driver after the HID bus using
late_initcall() in accordance with other hwmon HID drivers.
