Subject: [PATCH] soc: qcom: socinfo: add support for new fields in revisions
 20,21,22, and 23

add support for the below fields in socinfo structure:
- v20:
  * raw_package_type: type of the raw package
- v21:
  * partial_features_array_offset: position on array indexed by
    ChipInfoPartType, each bit notes the corresponding component being
    enabled or disabled
- v22:
  * cpu_cores_array_offset: position on array of cpu cores per cluster
- v23:
  * part_instances_offset: position on array of PlatformInfoPartInfoType
    structures
  * num_part_instances: length of the array of part_instances at
    part_instances_offset
