Michael Buesch 923fd7036f b43: Add debugfs firmware debugging knob
This adds a firmware debugging knob to debugfs.
With this knob it's possible to enable advanced runtime firmware
checks.
For now it only implements one sanity check for the mac-suspend.
In future there'll probably be more.
If CONFIG_B43_DEBUG is disabled, these checks will collapse to nothing.
