When built-in to the kernel, the corsair-psu driver fails to register with
the following message:
"Driver 'corsair-psu' was unable to register with bus_type 'hid'
because the bus was not initialized."
Fix this by initializing the driver after the HID bus using
late_initcall(), as hwmon is built before HID.
Fixes: d115b51e0e56 ("hwmon: add Corsair PSU HID controller driver")
