Changes: - Add EXPORT_SYMBOL_GPL for set/clear bus_protection and init functions - Remove static and __init qualifiers from mtk_infracfg_init - Add mtk_infracfg_init() declaration to header - Remove postcore_initcall, let dependent modules call init explicitly - Add #include for export macros - Add MODULE_LICENSE("GPL") metadata This allows mtk-infracfg to be built as a DDK module (.ko) and its functions to be used by other modules like mtk-scpsys for power domain management.
