ACPICA: Add acpi_update_interfaces() public interface
Add new API to allow OSPM to disable/enable specific types of _OSI interface strings. ACPICA does not have the knowledge about whether an _OSI interface string is an OS vendor string or a feature group string and there isn't any API interface to allow OSPM to install a new interface string as a feature group string. This patch simply adds all feature group strings defined by ACPI specification into the acpi_default_supported_interfaces with ACPI_OSI_FEATURE flag set to fix this gap. This patch also adds codes to keep their default states as ACPI_OSI_INVALID before the initialization and after the termination.
