/*
Sets the wirelss channel select options based on hw_mode and country_code.
Methodology: In North America up to channel 11 is the maximum allowed WiFi 2.4Ghz channel,
except for the US that allows channel 12 & 13 in low power mode with additional restrictions.
Canada allows channel 12 in low power mode. Because it's unsure if low powered mode can be
supported the channels are not selectable for those countries. Also Uzbekistan and Colombia
allow up to channel 11 as maximum channel on the 2.4Ghz WiFi band.
