mb/lenovo/{x230, x230s}: Disable SuperSpeed capabilities for WWAN USB

Although on ThinkPads with Panther Point PCH the usb port inside wwan
socket is usually wired to XHCI, it has actually no SuperSpeed lines,
so maybe it is okay to disable SuperSpeed capabilities, and wire them
to EHCI #2 by making use of XUSB2PRM and USB3PRM.

This applies to both variants of x230.
