The MediaTek AI Processing Unit (APU) is a proprietary hardware
in the SoC to support AI operations.
The series is to create apusys in the SoC folder for developing
the related drivers. Add the apu clocks, basic apu nodes and the
power domain to provide the power controller of APU subsystem.

This series is based on MT8192 clock[1] and MT8193/PMIC[3][4] patches.

[2] https://patchwork.kernel.org/patch/12134935
[3] https://patchwork.kernel.org/patch/12140237

Change notes:
v2->v3:
1) Rebase to 5.15-rc1
2) remove the apu-mbox registers from syscon.
3) update mtk-apu-pm to fix clock flow and move power status bit into
platform data to support different hardware settings.

v1->v2:
1) update expression "s/_/-/" in dt-bindings documents.
2) drop apu power domain header file for mt8192.

v1: https://patchwork.kernel.org/project/linux-mediatek/list/?series=461999
