power: supply: qcom_pmi8998_charger: fix wakeirq

[ Upstream commit 6c5393771c50fac30f08dfb6d2f65f4f2cfeb8c7 ]

Unloading and reloading the driver (e.g. when built as a module)
currently leads to errors trying to enable wake IRQ since it's already
enabled.

Use devm to manage this for us so it correctly gets disabled when
removing the driver.

Additionally, call device_init_wakeup() so that charger attach/remove
will trigger a wakeup by default.
