HACK: quick extremely dirty hack to get rid of warning SPAM

This simply avoids getting a shitload of warnings like this when
running on OMAP:

With this hack, it doesn't mean that your device will not crash to the
point of no return! Use it at your own risk.

mac80211: don't stop beaconing when going offchannel (INTERNAL)

wl12xx manages the channel per-role, so there is no need
to explicitly stop beaconing when doing offchannel operations,
as the device will take care of it by itself.

This way we avoid redundant stop_ap/start_ap calls when
doing offchannel operations on another vif (e.g. auth)

NOTE: this patch shouldn't go upstream. we have to come up
with more generic multi-channel solution...

wlcore/wl18xx/wl12xx: add version and timestamp strings (INTERNAL)

In order to allow better version control, add version
and timestamp strings into the wl12xx module.

These strings will be printed on driver load, and when
reading the driver_state.

(this is not going to work well in compat, because it
copies all the files instead of compiling them in the
original tree, so the version of the compat tree will
appear as the driver version. we can workaround it
with the additional makefile hacks...)

NOTE: I couldn't find how to make one module recompile
when the .h file of another module was changed, so i
just duplicated it for now.

wlcore: force recheck of version.h and use -dirty if needed (INTERNAL)

If the tree was changed and unstaged or if a new tag was added, we
were not regenerating the version.h file, so it would contain outdated
information.

To fix this, force the version.h file to be rechecked during make and
use __TIMESTAMP__ instead of using the shell's date command, so that
we don't regenerate it everytime.

Additionally, use --dirty in git describe to mark dirty trees as such.

Thanks Eliad for the help with this.

wlcore/wl12xx/wl18xx: don't force version check everytime (SQUASH)

With compat-wireless, we shouldn't force the version.h file checks,
otherwise it will overwrite what we generated in compat-wireless
itself.  This was only needed for dirty trees anyway.  The side-effect
is that the version will not be regenerated when the tree becomes
dirty.

Should be squashed with c062da59.
