platform/x86: ISST: Support partitioned systems
A partitioned system has two different PCI VSEC devices per package. A non-partitioned device has only one PCI VSEC device per package. The current implementation only supports non partitioned systems. Each partition maps a set of power domains. Other than reading from different MMIO regions, there is no change in the SST functionality. The scope of SST control is still per power domain. Hence user space does not need to be aware of existence of partitions. With partitions, existing per package information defined using struct tpmi_sst_struct is enhanced to store information for both partitions. A mapping function map_partition_power_domain_id() is introduced, which maps to correct partition and index. This mapping function is called in get_instance() and isst_if_clos_assoc(), before indexing into tpmi_sst_struct->power_domain_info[]. The TPMI core platform info provides partition id and compute die ID mask for each partition. Use this information to order power domains, so that compute dies are presented before IO dies to match hardware defined compute die ID for each CPU.
