remove redundant paragraph

the paragraph in question largely pertains to
the ivybridge and sandybridge latitudes in libreboot,
not the gm45 latitudes supported in both libreboot
and canoeboot. remove this paragraph (instead of adding
the missing article).

nobody ever reported such issue on the gm45 model, only
the ivy/sandy models.
