usb: usb251xb: Add 5,6,7 ports mapping def setting
USB2517 got three additionl downstream ports, which can as well be mapped to another logical ports. USB251xb driver currently doesn't fully support such setting configuration from dts file. This patch doesn't change this, but adds usb2517 spcific ports default liner mapping.
