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.
