[PATCH v5 0/3] Add mt8189 dts evaluation board and Makefile

[Sirius Wang]

We add basic chip support for Mediatek MT8189 on evaluation board.

In this series, we also add dt-bindings document definition for MT8189.

This series is based on tag: next-20250717

Changs in v5:
 - remove unused cpu-dile-state definition.
 - change memory size in "reg" property which if filled in by bootloader.

Changs in v4:
 - Correct cpu-idle-states.
 - Change the "reg" property name of the "memory" node in the
   device tree source (DTS) to lowercase.

Changs in v3:
 - Move ulposc and ulposc3 before cpu nodes.
 - Refactor cpu-map to a single cluster0.
 - Change cpu nodes name from medium core to big core.
 - Move psci before timer nodes.

Changs in v2:
 - Fix warning issues for make CHECK_DTBS=y.
 - Add mediatek,uart.yaml document.
