On a QCOM based SoC, this info can be obtained from socinfo debugfs infrastructure. For this to work, respective subsystem drivers have to export the firmware version information to an SMEM based version information table. Having firmware version information at one place will help quickly figure out the firmware versions of various subsystems on the device instead of going through builds/logs in an event of a system crash. Fill WLAN firmware version information in SMEM version table to be printed as part of socinfo debugfs infrastructure on a Qualcomm based SoC. This change is applicable only for WCN399X targets.
