mac80211 doesn't use dev_dbg() but instead various macros from
net/mac80211/debug.h. Adjust wbrf code to use wiphy_dbg() instead.

This won't work, I still see the debug message:
[ 333.765867] ieee80211 phy0: WBRF is not supported
The issue seems to be that mac80211 defines DEBUG in
net/mac80211/Makefile:
ccflags-y += -DDEBUG
That -DDEBUG should be cleaned up, but I think separately. It's just
that I cannot come up with any good proposal, all the macros in
net/mac80211/debug.h require sdata and we don't have that in this stage.
Any ideas?

I will submit a patch that only compiles wbrf.c when CONFIG_AMD_WBRF=y

But does this mean that the debug is still printed when CONFIG_AMD_WBRF
is enabled? And I would assume all distros enable that, right?

Maybe just discard the debug message instead of have to deal with this.
We'll be able to tell from the consumer (amdgpu right now) when WBRF is
being used and if we need to debug an issue knowing that it's supported
or not supported from the producer side is the least of our worries.

Yeah, removing the message for now is the best solution. It can be added
later after we have improved mac80211 logging.
