ath10k: add hw_rev to trace events to support pktlog
pktlog data is different between firmware variants (eg. 10.2 vs 10.4). To have a unified user space script to decode pktlog trace events generated, it is desirable to know which firmware variant has provided the events and thereby decode the pktlogs appropriately. Hardware revision (hw_rev) helps to determine the firmware variant sending these trace events. So add hw_rev to trace events.
