[PATCH] riscv: dts: spacemit: drop unnecessary power supply from PCIe

[Yixun Lan]

The PCIe Root Complex found on the SpacemiT K1 SoC does not require
external power supply, this match with the dt-binding documentation[1],
Instead it's the sub node of PCIe ports which should add vpcie3v3 power
supply. So, explicitly remove "vpcie3v3-supply" property from the PCIe
controller.

The problem was introduced at the time of PCIe DTS first committed to
kernel, the vpcie3v3-supply should be added to PCIe ports instead of PCIe
RC node.

Refer the example dts of Documentation/devicetree/bindings/pci/spacemit,k1-pcie-host.yaml

I'm not adding the Fixes tag, as this doesn't cause any severe bug, thus
not necessary to do the back port..
