[PATCH v3 3/4] mailbox: mtk-cmdq: Add cmdq driver for mt8189

[Xiandong Wang <xiandong.wang@mediatek.com>]

Add GCE platform data for MediaTek MT8189 to cmdq driver,
enabling support for MT8189 SoC by register MT8189 platform
data in gce_plat and device table.

These changes ensure correct GCE operation for MT8189.
