Subject: [PATCH 5.11 154/775] arm64: dts: mt8183: Add missing power-domain for pwm0 node

From: Enric Balletbo i Serra <enric.balletbo@...labora.com>

[ 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.
