If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/power/supply/max8997_charger.ko | grep alias
$

After this patch:

$ modinfo drivers/power/supply/max8997_charger.ko | grep alias
alias:          platform:max8997-battery
