drivers:usb: Add device-tree fixup to identify socs having dual phy
Identify soc(s) having dual phy so as to add "utmi_dual" as phy_mode for all these socs. This is required for supporting deel-sleep feature in linux for usb driver Signed-off-by: Ramneek Mehresh <ramneek.mehresh@freescale.com> Signed-off-by: Nikhil Badola <nikhil.badola@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
