I'm totally agree with merging this patch to the usage parts of mtk-
cmdq-sec-mailbox.c.

But I have no idea why mtk-cmdq-sec-mailbox.c and mtk-cmdq-mailbox.c
are not placed in the same maintainer's tree as mtk-cmdq.h and mtk-
cmdq-helper.c, so I just separate them to different patch by tree like
the requirement from previous sent series.

I will re-organized this series to make the definition and the usage of
the code in the same patch.
