ACPI: battery: Fix system wakeup on critical battery status

Browse Source 
Commit 0a869409a9 ("ACPI: battery: Convert the driver to a platform
one") changed the parent of the battery wakeup source to the platform
device used for driver binding, but it forgot to update the
acpi_pm_wakeup_event() call in acpi_battery_update() accordingly.

Do it now to unbreak waking up the system on critical battery status
during suspend-to-idle and during transitions to ACPI S3/S4.

Fixes: 0a869409a9 ("ACPI: battery: Convert the driver to a platform one")
