mb/lenovo/x131e: Clean up USB configurations

As of commit a911b7584820 ("mb/*: Remove old USB configurations from
SNB/bd82x6x boards") USB configurations are drawn exclusively from
devicetree. The old copy carried by early_init.c should have been
removed back then. Since it has nothing else, drop the whole file.

Remove xhci_overcurrent_mapping as it is now derived from
usb_port_config.

According to schematics only the first two ports are wired for xHCI
and both goes to OC0#. Remove OC pin assignment from disabled third
port so the (former) xhci_overcurrent_mapping can be derived
correctly. Also adjust xhci_switchable_ports and
superspeed_capable_ports to match.

Thanks to Patrick Rudolph for the information.
