All legacy platform data now can be parsed from DT. Because of that and since SMB347 is an I2C client driver, the IRQ number can be passed automatically through client's IRQ variable if it's defined in DT. There is no need to map GPIO to IRQ manually in the case of DT.

Secondly, power-supply core now supports monitored-battery. So the 'fake' battery doesn't do anything useful for us, and thus, it should be removed. Transfer smb347-battery functionality into smb347-mains and smb347-usb.
