this patch is a small preparation to fix isp1301 driver so that other platforms can use it.
We're defining our private data structure to represent this device and adding the PHY to the PHY list. Later patches will come implementing proper PHY API and removing bogus code from ohci_nxp and lpc32xx_udc drivers.
