hw/imc: Fix the pvr (sub_id) for IMC Catalog load
Currently IMC catalog carry multiple dtbs in the pnor partition, one for each power9 major versions. And system pvr value (pvr_type and pvr_major version) is used as sub-id to load the right dtb from the partition. Since minor version of pvr is not used, mask it out.
