Armada CP110 UTMI supports swapping D+ and D- signals.
usb251xb.yaml already describes a suitable device-tree property for the
same purpose but as child usb controller node.
Add optional swap-dx-lanes device-tree property to armada cp110 utmi phy
with same semantics as usb251xb:
The property lists all ports that swap D+ and D-, unlisted ports are
considered correct.
