Subject: [PATCH 0/4] wcn36xx: Add in debugfs export of firmware feature bits
This series tidies up the code to get/set/clear discovered firmware feature
bits and adds a new debugfs entry to read the feature bits as strings.

This is a handy way of debugging WiFi on different platforms without
necessarily having to recompile to see the debug printout on firmware boot.
