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.

Can we change this to u64 instead?
With that done,
