Change subject: Return init error for invalid values of pullups, hiz, psus
......................................................................

Return init error for invalid values of pullups, hiz, psus

Previously, invalid values of the params pullups, hiz, psus were handled as "off" (i.e. disabled). This created a potential human error when users were running flashrom with e.g. pullups=1 and expected pullups to be on, while the value 1 was handled as invalid and off.
