Hmm, you want to have DEBUG_FS support always enabled? I was expecting
to have it enabled behind a driver debug option as it should not be
needed during normal usage. I also expected the firmware_verify function
to be triggered from there but I don't have a string opinion on that one.
The Kconfig setup misses a "depends on DEBUG_FS".
Well - most debugfs function have empty return -ENODEV function stubs in
case CONFIG_DEBUG_FS is not set.
It was done to avoid the ifdef and depends mess.
So this can stay the way it is.

Besides the question about having DEBUG_FS enabled by default I think
this one is fine now to go in.

I will do some testing on the hardware later today and scream if
something strange shows up.
