Add Support for MediaTek MT8192 APU.

The MediaTek AI Processing Unit (APU) is a proprietary hardware
in the SoC to support AI functions.
The patches support the MT8192 APU running on internal microprocess.
Software packages contins power control, tinysys controller and middleware.

This series is based on drivers implemented in
MT8192 apu power domain[1] and IOMMU[2] patches.
