From: Luciano Coelho <luciano.coelho@xxxxxxxxx>
Instead of simply not scanning for the 11a channels when not supported by the
hardware, disable the channels in reg_notify. This centralizes the decision
on whether to scan 5GHz channel in one place and allows userspace to know
exactly which channels are in use.
Based on Juuso Oikarinen's idea.
