Subject: [PATCH 1/2] soc: qcom: socinfo: Add support for new fields in revision 18

Add support for below fields coming in socinfo structure under v18:
* num_kvps: number of key value pairs (KVP)
* kvps_offset: the offset of the KVP table from the base address of
  socinfo structure in SMEM
KVP table has boolean values for certain feature flags, used to determine
hardware configuration.
