ACPI / AC: Remove struct acpi_device pointer from struct acpi_ac
Now the pointer of struct acpi_device can be got by ACPI_COMPANION(struct acpi_ac->pdev->dev). So the pointer is not necessary and remove it. Signed-off-by: Lan Tianyu <tianyu.lan@intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
