mb/dell/snb_ivb_latitude: Move E6430 USB config to devicetree

As of commit ee12634872 (nb/sandybridge,sb/bd82x6x: Configure USB from
southbridge devicetree) and earlier commits, the USB port configuration
should be located in the devicetree instead of the mainboard_usb_ports
array, typically located in the boards early_init.c.

TEST=USB ports still function; and the USBIRx, USBPDO, USBOCM1, and
USBOCM2 RCBA registers in the inteltool dump did not change between
an E6430 build before and after the sb/intel/bd82x6x that moved the
usb config to the devicetree.
