Subject[014/116] ath5k: dont use external sleep clock in AP mode
2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Bob Copeland <me@bobcopeland.com>

commit 5d6ce628f986d1a3c523cbb0a5a52095c48cc332 upstream

When using the external sleep clock in AP mode, the
TSF increments too quickly, causing beacon interval
to be much lower than it is supposed to be, resulting
in lots of beacon-not-ready interrupts.

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=14802.
