soc: mediatek: mutex: add functions that operate registers by CMDQ

Due to HW limitations, MDP3 is necessary to enable MUTEX in each frame
for SOF triggering and cooperate with CMDQ control to reduce the amount
of interrupts generated(also, reduce frame latency).

In response to the above situation, a new interface
"mtk_mutex_enable_by_cmdq" has been added to achieve the purpose.

soc: mediatek: mutex: add common interface for modules setting

In order to allow multiple modules to operate MUTEX hardware through
a common interfrace, two flexible indexes "mtk_mutex_mod_index" and
"mtk_mutex_sof_index" need to be added to replace original component
ID so that like DDP and MDP can add their own MOD table or SOF
settings independently.

In addition, 2 generic interface "mtk_mutex_write_mod" and
"mtk_mutex_write_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.
