arm64: dts: ls1043a: use a pseudo-bus to constrain usb and sata dma size
Wrap the usb and sata controllers in an intermediate simple-bus and use it to constrain the dma address size of these usb controllers to the 40 bits that they generate toward the interconnect. This is required because the SoC uses 48 bits address sizes and this mismatch would lead to smmu context faults because the usb generates 40-bit addresses while the smmu page tables are populated with 48-bit wide addresses.
