product/rd*: add cmn600/cmn650 mapping for 64-bit pcie mmio addr space

Created by: vijayenthiran-arm

The devices accessed on the PCIe topology so far have required only 32-bit PCIe MMIO accesses. But with devices such as SMMUTE which requires 64-bit BAR region, there is a need to map the 64-bit PCIe MMIO region as well. To allow the access to the 64-bit PCIe MMIO region from the requesting nodes, add 4 GiB region starting at 0x05_0000_0000 and set HND as target node.
