[PATCH 2/8] ASoC: SOF: Add `src_hash` to `sof_ipc_fw_version` structure

[Kai Vehmanen <kai.vehmanen@linux.intel.com>]

From: Karol Trzcinski <karolx.trzcinski@linux.intel.com>

This field will be used to compare ldc file with loaded fw version,
to assert validity of trace logs. Value used in sof-logger.
