rS358818: acpi: Fix stalled value returned by acpi_get_device() after device deletion

Summary

Newbus device reference attached to ACPI handle is not cleared when newbus device is deleted with devctl(8) delete command. That leads to kernel crashes in iicbus ACPI-based enumerator (https://reviews.freebsd.org/D22901) after acpibus-hosted device has been deleted.
Fix that with calling of AcpiDetachData() from "child_deleted" bus method exactly like acpi_pci driver does.
