AIE (AI Engine) is one of the units in MT8188 ISP which provides
hardware-accelerated face detection function. It can detect different
sizes of faces in a raw image using pyramid-based multi-scale detection.

The AIE supports three operation modes:
- Face Detection (FD): Multi-scale face detection using 3-level pyramid
  (640x480 base, 2x downscale per level).
- Attribute Analysis: Age, gender, and race classification.
- Facial Landmark Detection (FLD): 11-point landmark localization using
  Binary Tree Traversal on FD results.

Changes in v6:
- DT binding: Add ipe-smi-larb12 clock, remove iommus from required
  properties, add mediatek,larb as optional, improve description.
- DTS: Remove iommus and mediatek,larb properties, fix IRQ number.
- UAPI: Simplify header to control ID definitions only, drop custom
  V4L2_CTRL_TYPE (use V4L2_CTRL_TYPE_U32 compound controls instead).
- Driver: Fix NULL pointer check inversion, fix resource leaks on error
  path, remove debugfs return value checks, update clock names to hyphen
  convention, remove freq_level per CK Hu's feedback.

Changes in v5:
- DT binding: Use hyphens in clock names, remove mediatek,larb.
- UAPI: Add feature_threshold docs, rename structures, move structures
  from mtk_aie.h to uapi header.
- Driver: Update clock names, improve error handling in probe.

Changes in v4:
- DT binding: Remove address-cells/size-cells, remove larb12 content.
- UAPI: Add V4L2_META_FMT_MTFD_RESULT documentation.
- Driver: Remove larb12 related content.

Changes in v3:
- DTS: Remove non-MMIO nodes.

Changes in v2:
- Fix coding style issues throughout.
