AP: Add op_class config item to specify 6 GHz channels uniquely

Browse source 
Add hostapd config option "op_class" for fixed channel selection along
with existing "channel" option. "op_class" and "channel" config options
together can specify channels across 2.4 GHz, 5 GHz, and 6 GHz bands
uniquely.
