Wellsburg is IFDv2 compatible in most fields, but not in all. It only has 8 regions and the flash master bits match the defines for IFDv1 and thus has an "IFDv1.5" descriptor. Add a new enum for IFDv1.5 descriptor and use them to properly operate on this IFD. The 'SPI programming guide' is inconsistent and mentions 6 regions in one place, but 7 regions in another chapter. Tests showed that it actually supports 7 regions. Add support using the -p argument to specify Wellsburg platform. The previous patch made sure that only 8 regions are used and that no corruption can happen when operating in IFDv2/IFDv1.5 mode. Tested on Intel Grangeville.
