Notes:
v1->v2:
Change my Signed-off-by from "Zhou Yanjie <zhouyanjie@xxxxxxxx>"
to "周琰杰 (Zhou Yanjie) <zhouyanjie@xxxxxxxxxxxxxx>" because
the old mailbox is in an unstable state.
v2->v3:
Adjust order from [3/5] in v2 to [4/5] in v3.
v3->v4:
Adjust order from [4/5] in v3 to [3/4] in v4.
v4->v5:
Rebase on top of kernel 5.6-rc1.
v5->v6:
Add missing part of X1830's CGU.
v6->v7:
No change.
