CHROMIUM: ath10k: Add support to parse fwlog for mac address
Host receieves fwlog from firmware along with arguments of
4byte values. Since the mac address is of 6bytes value,
it is splited as two arguments and send it host. To make
it readable format print the mac address in a single argument
by parsing the FWLOG string where firmware sends the mac address
as two arguments
Note: This change works properly on FW version 3.9.0.2.131
and above in QCA9984.
