In order to allow multiple modules to operate MUTEX hardware through a common interfrace, a flexible index "mtk_mutex_table_index" needs to be added to replace original component ID so that like DDP and MDP can add their own MUTEX table settings independently. In addition, 4 generic interface "mtk_mutex_set_mod", "mtk_mutex_set_sof", "mtk_mutex_clear_mod" and "mtk_mutex_clear_sof" have been added, which is expected to replace the "mtk_mutex_add_comp" and "mtk_mutex_remove_comp" pair originally dedicated to DDP in the future.
