[ Upstream commit 46c56b737161060dfa468f25ae699749047902a2 ]

The pcie bus address should be mapped 1:1 to the cpu side MMIO address, so
that there is no same address allocated from normal system memory. Otherwise
it's broken if the same address assigned to the EP for DMA purpose.Fix it to
sync with the vendor BSP.

Fixes: 0acf4fa7f187 ("arm64: dts: rockchip: add PCIe3 support for rk3588")
Fixes: 8d81b77f4c49 ("arm64: dts: rockchip: add rk3588 PCIe2 support")
