power: supply: max14656: fix potential use-before-alloc
Call order on probe():
- max14656_hw_init() enables interrupts on the chip
- devm_request_irq() starts processing interrupts, isr
could be called immediately
- isr: schedules delayed work (irq_work)
- irq_work: calls power_supply_changed()
- devm_power_supply_register() registers the power supply
Depending on timing, it's possible that power_supply_changed()
is called on an unregistered power supply structure.
Fix by registering the power supply before requesting the irq.
