Do you mean I should merge the patch 12 and 13?

I think separating the new supported mt8188 and the new supported
secure feature in different patch can make the CMDQ user know how to
make a CMDQ mailbox driver support secure feature.

Since mt8188 is a new supported IC for mailbox, so merging patch 12 and
13 into the same patch is OK.
I'll merge them at the next version. Thanks.
