ata: ahci_xgene: free structure returned by acpi_get_object_info()
acpi_get_object_info() allocates the returned structure, which the caller has to free when the call succeeds. Free it when appropriate. Fixes: c9802a4be661 ("ata: ahci_xgene: Add AHCI Support for 2nd HW version of APM X-Gene SoC AHCI SATA Host controller.")
