Subject: [PATCH] soc: qcom: socinfo: Add support for new fields in revision 16

Add support for new fields coming with socinfo structure under v16 to get
SKU information, product code and name and type of different parts present
in the SoC. Also, add debugfs nodes to read feature and product codes to
allow user to get SKU and other SoC details. Support for SoC parts name
and type parsing will be added separately. Details of fields added:
* feature_code: mapped to qcom internal and external SKU IDs
* pcode: product code
* npartnamemap_offset: parts name map array offset from socinfo base ptr
* nnum_partname_mapping: number of part mappings
