Please keep the nodes sorted in unit-address.

Do you mean to move the node 'usb1: usb2@8600000' forward to where it's address is just before '@8600000 '?
I think it's reasonable to put USB controller nodes together in DTS for developer to do issue analysis.

The nodes under simple-bus are maintained in order of unit-address.
Please respect that.

usb2@8600000 should go after sata@3200000 with the current nodes.
