ACPICA: Deploy ACPI_EXPORT_SYMBOL_INIT for main ACPICA initialization interfaces.
This changes can reduce source code differences between Linux and ACPICA upstream to help improving the release automation. The side effect of applying this patch in Linux is: 1. Some ACPICA initialization/termination APIs are no longer exported in Linux, these include: acpi_load_tables acpi_initialize_subsystem acpi_enable_subsystem acpi_initialize_objects acpi_terminate 2. This patch does not affect the following APIs as they are currently not marked with ACPI_EXPORT_SYMBOL in Linux: acpi_reallocate_root_table acpi_initialize_tables Such functions should not be exported as they are internal to ACPI subsystem in Linux, and will only be invoked inside of ACPI subsystem's initialization routines marked with __init and termination routines marked with __exit. While on other OSPMs, such functions may still need to be exported. Thus this patch adds the configurability for ACPICA, so that it leaves OSPMs to determine if the __init/__exit marked functions should be exported or not. Lv Zheng.
