This patch series adds support for the MediaTek MT8196 SoC's display
subsystem in the DRM driver.

Changes in v2:
- add support for MT8196's new hardware components (EXDMA, BLENDER, 
  OUTPROC) following the previous MTK OVL software architecture.
- reuse mtk_ovl drivers in MediaTek DRM display to support the new 
  MT8196 SoC.
- implement support for multiple mmsys instances within a single 
  mediatek-drm driver, improving flexibility and scalability.
- refactor existing components (mutex, OVL) to accommodate the new 
  architecture and improve code reusability.
- update component matching, binding logic, and data structures to 
  support the new multi-mmsys design.
