arm64: dts: mt8183-kukui: clean up regulator tree

Browse Source 
Some regulators in the kukui device tree are modeled incorrectly. Some
are missing supplies and some switches are incorrectly modeled as
voltage regulators. A pass-through was incorrectly modeled as a
regulator.

Add supplies where missing, remove voltage constraints for "switches",
and drop the "bl_pp5000" pass-through.

This depends on commit 2a99858c17 ("arm64: dts: mediatek: mt8183-kukui:
Add PMIC regulator supplies") for reg_vsys.

Fixes: cd894e274b ("arm64: dts: mt8183: Add krane-sku176 board")
Fixes: f15722c0fe ("arm64: dts: mt8183: Add pwm and backlight node")
