witherspoon: Fix VPD EEPROM type
There are userspace tools that update the planar VPD via the sysfs interface. Currently we do not get correct information from hostboot about the exact type of the EEPROM so we need to manually fix it up here. This needs to be done as a platform specific fix since there is not standardised VPD EEPROM type.
