ACPICA: Add __init for ACPICA initializers/finalizers.

This patch adds __init to the ACPICA documented initializers: acpi_initialize_tables() acpi_initialize_subsystem() acpi_load_tables() acpi_enable_subsystem() acpi_initialize_objects() and to acpi_reallocate_root_table(), acpi_find_root_pointer() which are also meant to be called only during initialization. This patch adds __init to the ACPICA documented finalizer: acpi_terminate() as this finalizer is only called in __init function now. This change helps to reduce source code differences between ACPICA upstream and Linux. [rjw: Changelog] Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.
