Subject: [PATCH 2/2] soc: qcom: socinfo: Add support for new fields in revision 19

Add support for below fields coming in socinfo structure under v19:
* num_func_clusters: number of clusters with at least one functional core
* boot_cluster: cluster selected as boot cluster
* boot_core: core selected as boot core
While at it, rename some variables to align them with their
functionalities.
