wifi: mac80211_hwsim: modernise S1G channel list

Browse Source 
The current S1G channel list in mac80211_hwsim does not represent
what S1G drivers would advertise that being 1MHz primaries. Also,
include the NO_PRIMARY flag on the edgeband 1MHz primaries to emulate
US operation such that it can also be tested.
