arm64: dts: mediatek: mt8183-kukui: Drop bogus fixed regulators

Browse source 
A couple of the fixed regulators in the Kukui dtsi do not actually
exist in the hardware design; they are simply power rails connected
together with 0 ohm bridges.

Drop them and assign their upstream supplies to their consumers instead.
