[PATCH 1/2 v2] ar9170: cleanup of bss_info_changed and beacon config

[Joerg Albert <jal2@xxxxxx>]

Add beacon control by BSS_CHANGED_BEACON_ENABLED and
bss_conf->enable_beacon from mac80211.

Signed-off-by: Joerg Albert <jal2@xxxxxx>

---

As suggested by Christian this version preserves the old behaviour for STA mode.
