riscv: dts: spacemit: Add 'linux,pci-domain' to PCIe nodes for K1

Browse source

The SpacemiT K1 SoC has 3 PCIe EP controller nodes. Add the
'linux,pci-domain' property to assign a PCI domain number to
each of the controllers instead of assigning it randomly.

This creates a stable sysfs path, allowing userspace scripts
to reliably target specific PCIe devices (such as PCIe NICs).
