[PATCH v1 2/3] soc: qcom: smem: Added socinfo header file

[Aswin Murugan]

From: Varadarajan Narayanan <varadarajan.narayanan at oss.qualcomm.com>

Added socinfo header file from linux [1]. This header
defines SoC ID constants, version macros, and helper APIs for querying
SoC details such as ID, revision, and features at runtime. It enables
platform-specific initialization and feature gating based on SoC info.
