trace: Log FW ABI and hash numbers 

This log allows to fully identify source code and check ldc
compatibility with FW by comparing source hash value saved in ldc
file with value received from FW in runtimee.
Without this mechanism it's impossible to
be sure about right connection without booting firmware
(to read fw_ready message content), because value of fw_hash
hasn't been provided in output logs file. This is especially
important during debugging process based on logs received by
client.
