[ Upstream commit 2f99fb6e46b0e982bb6ab18b24a08fa318f740ea ]
The MT8183 display PWM device will not work until the associated
power-domain is enabled. Add the power-domain reference to the node
allows the display PWM driver to operate and the backlight turn on.
Fixes: f15722c0fef0 ("arm64: dts: mt8183: Add pwm and backlight node")
