[PATCH v2 10/16] arm64: dts: mediatek: mt8195-cherry: Add MT6315 PMIC supplies

The MT8195 Cherry design has two MT6315 PMICs. One has 4 outputs ganged
together; the other has 2 outputs ganged together, and the other two
unused.

Add supplies for these two PMICs. Since the outputs are ganged together,
just add the supply for the first one.

Signed-off-by: Chen-Yu Tsai <wenst@chromium.org>

Changes since v1:
- Moved supplies to PMIC top level node
- Added all supplies

All supplies are connected, but since the regulators are ganged
together, only one regulator node is present.
