Subject: [PATCH v9 0/3] firmware: mtk: add adsp ipc protocol for SOF

This patch provides mediatek adsp ipc support for SOF.
ADSP IPC protocol offers (send/recv) interfaces using
mediatek-mailbox APIs.

This patch was tested and confirmed to work with SOF fw on 
MT8195 cherry board and MT8186 krabby board.

changes since v8:
- fix patchset 2 and 3.
  move "depends on MTK_ADSP_IPC" from SND_SOC_SOF_MTK_COMMON
  to SND_SOC_SOF_MT8195/MT8186 to prevent generating wrong
  config.

changes since v7:
- rebase to linux-next/next-22020504
- use EXPORT_SYMBOL_GPL instead of EXPORT_SYMBOL in mtk-adsp-ipc.c 
- move mtk-adsp-ipc.c out from driver/firmware/mediatek
- add user of mtk-adsp-ipc.h in patchset 2 and 3.

changes since v6:
- rebase to matthias.bgg/linux.git, v5.18-next/soc
- Prefer "GPL" over "GPL v2" for MODULE_LICENSE

changes since v5:
- fix WARNING: modpost: missing MODULE_LICENSE() in drivers/mailbox
  /mtk-adsp-mailbox.o. Add MODULE_LICENSE in the last line.
- Due to WARNING: Missing or malformed SPDX-License-Identifier tag
  in line 1 in checkpatch, we don't remove SPDX-License in line 1.

changes since v4:
- add error message for wrong mbox chan

changes since v3:
- rebase on v5.16-rc8
- update reviewers

changes since v2:
- add out tag for two memory free phases

changes since v1:
- add comments for mtk_adsp_ipc_send and mtk_adsp_ipc_recv
- remove useless MODULE_LICENSE
- change label name to out_free
