[PATCH v3 21/21] pmdomain: mediatek: Add power domain driver for MT8189 SoC

[irving.ch.lin <irving-ch.lin@mediatek.com>]

From: Irving-CH Lin <irving-ch.lin@mediatek.com>

Introduce a new power domain (pmd) driver for the MediaTek mt8189 SoC.
This driver ports and refines the power domain framework, dividing
hardware blocks (CPU, GPU, peripherals, etc.) into independent power
domains for precise and energy-efficient power management.
