nb/intel/gm45: Export low-power and (SFF) options
Make the low-power and small form factor (SFF) options overridable
from romstage main. Also disable both options by default. That's ok
as there aren't yet any in-tree users of the GS45 chipset. As a nice
side-effect, this adds X200s support to the lenovo/x200 port.
