This info is already available under debugfs although I prefer your
formatting :-) :
$ sudo cat hardware
board vendor: 1028
board type: e
board revision: 2203
board flags: 200
board flags2: 1000
firmware revision: 262032c

I used the same formating b43 uses, I do not know what's the official
formating for this firmware version number.
Writing the firmware version to wiphy->fw_version is the official way to
do this and many drivers already are exporting their firmware version in
this way.
I would prefer export the firmware version this way and also add it to
the hardware info in debugfs, where it already is.
