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.
