Laurentiu Tudor c68535657f arm64: dts: ls208xa: use a pseudo-bus to constrain usb dma size 
[ Upstream commit b39d501645 ]

Wrap the usb controllers in an intermediate simple-bus and use it to
constrain the dma address size of these usb controllers to the 40b
that they generate toward the interconnect. This is required because
the SoC uses 48b address sizes and this mismatch would lead to smmu
context faults [1] because the usb generates 40b addresses while the
smmu page tables are populated with 48b wide addresses.
