Alternative patch for hardware/broadcom/wlan

This is a cleaner fix for the broad wlan private commands problem.
It should be used as a replacemment for
0001-Make-nl80211-driver-to-quietly-ignore-private-comman.patch

It's a temporary fix until external/wpa_supplicant_8,
hardware/libhardware_legacy and hardware/broadcom/wlan are all in
sync.

To use:

% cd $ANDROID_BUILD_TOP/hardware/broadcom/wlan
% repo start syncstructs .
% git am $ANDROID_BUILD_TOP/device/ingenic/npm801/0001-DO-NOT-SUBMIT-Synchronise-driver_nl80211.h-with-PDK-.patch
