For instance, starting from version v1.0.0 to v2.0.1 the offsets are same. And starting from v2.1.0, the offsets changed. But the current reg_offset naming convention is confusing. So to reflect this change correctly in driver, let's encode the start version from which the offsets got changed in reg_offset struct name. This will be llcc_v1_reg_offset for v1.0.0 and llcc_v2_1_reg_offset for v2.1.0. This will allow multiple SoCs to use the same reg_offset clearly. And in the future if the offsets got changed again, then that specific version could be encoded in the struct name.
