arm64: dts: rockchip: fix rk3576 pcie1 linux,pci-domain

pcie0 already used 0 as its pci-domain, so pcie1 will fail to
allocate the same pci-domain if both of them are used.

rk-pcie 2a210000.pcie: PCIe Link up, LTSSM is 0x130011
rk-pcie 2a210000.pcie: PCIe Gen.2 x1 link up
rk-pcie 2a210000.pcie: Scanning root bridge failed
rk-pcie 2a210000.pcie: failed to initialize host
