fsp_baytrail: Allow selection of USB controller by get_option

It was requested to be able to update XHCI vs EHCI via get_option,
    so I've added it here for minnow max.  This could get moved to the
    chipset_fsp_util.c file later, but I'm adding it here for now.

More checking needs to be added to this:
    - Are both controllers enabled in devicetree?  If not, we don't want
    to allow the switch.
