soc/alderlake/romstage: Set UsbTcPortEnPreMem UPD based on devicetree
The UsbTcPortEn UPD for FSP-S is being set in ramstage, however the equivalent FSP-M UPD, the UsbTcPortEnPreMem, was not being set. Following the Meteor Lake example, set the UsbTcPortEnPreMem UPD as well for Alder Lake. Setting this FSP-M UPD will cause FSP to properly program sideband use BSSB_LSx pins for the enabled Type-C ports. Required for proper DCI debug and TCSS initialization flow.
