[PATCH 2/2] zd1211rw: enable an AP that can't support fully PS clients (wireless-testing).

["Rami Rosen" <ramirose@gmail.com>]

This patch enables master mode support in zd1211rw driver and enables
it to support the PS challenged mode when used in master mode.

It adds this functionality in the zd1211rw driver by adding support to
master mode (NL80211_IFTYPE_AP) in zd_op_add_interface() and in
zd_mac_alloc_hw() methods
of drivers/net/wireless/zd_mac.c.

In addition, the new boolean member of wiphy struct, ap_ps_challenged,
is initialized to true in zd_mac_alloc_hw().
