The driver registers ltc4283_of_match as the platform driver's
.of_match_table so the kernel probes the device when a DT node with
compatible "adi,ltc4283" is present, but the corresponding
MODULE_DEVICE_TABLE(of, ...) call is absent.
Without it the module alias table (modules.alias) does not contain an
"of:N*T*Cadi,ltc4283" entry, so udev / kmod cannot auto-load the
module when the DT node appears, breaking modules-based deployments
while built-in configurations happen to work by accident.
Add the missing MODULE_DEVICE_TABLE() to fix module auto-loading.
Fixes: dd63353a0b5e ("hwmon: ltc4283: Add support for the LTC4283 Swap Controller")
