wext: make sysfs bits optional and deprecate them

The /sys/class/net/*/wireless/ direcory is, as far as I know, not
used by anyone. Additionally, the same data is available via wext
ioctls. Hence the sysfs files are pretty much useless. This patch
makes them optional and schedules them for removal.

         to keep working over the upgrade to 2.6.26. At the scheduled time of
         removal fixed lm-sensors (2.x or 3.x) should be readily available.
