[PATCH v4 12/12] arm64: dts: mediatek: mt8183-kukui: Add PMIC regulator supplies

[Chen-Yu Tsai <wenst@xxxxxxxxxxxx>]

The PMIC regulator node is missing regulator supplies. Now that the
binding supports them, add all the power rail supplies. Most of them
are fed from a system-wide semi-regulated power rail. A couple LDOs
are fed from the PMIC's own buck regulator outputs.
