From: Johannes Berg <johannes.b...@intel.com>
Instead of having to list all the hw flags in many places, just
list the macro to generate everything in a new include file and
include it in the proper places.
Unfortunately this breaks docbook processing since that doesn't
pre-process the file. It also doesn't generate the necessary
Kconfig items.
