From: Johannes Berg <johannes.berg@xxxxxxxxx>
Contrary to what was stated before, the hardware hasn't changed
the bits here yet. In any case, the new CSR is also directly
(lower 16 bits) connected to UREG_DOORBELL_TO_ISR6, so if it
still changes the changes would be there. Adjust the code and
comments accordingly.
