wifi: mac80211_hwsim: Add 160MHz bw range to regdom_custom_04

This allows testing 160MHz channels with DFS concurrent.
While at it, remove the TODO for adding a module param to enable
NL80211_EXT_FEATURE_DFS_CONCURRENT. This is not really needed as
mac80211_hwsim still needs to be loaded with custom regdom.
