During random channel selection after radar, channels 149 to 177 are
not considered as a potential random HT160 channel after the
introduction of the 5.9G channels. This is because, the last 80MHz
band (165, 169, 173, 177) are not added to the list of 80MHz band
list that is used to find the next random channel.
Update the 80MHz band list with 165-177 and update the band count.
