net/ieee802154: Add Sub-Ghz dedicated function on the radio API

Browse source 
Sub-Ghz bands have different limit of channels. 10, or more than a
thousand is actually possible. Thus the device needs to expose such
limit to the L2 which is unaware of frequency band logic. L2 will
then allow user to select a proper channel.

Enable support for Sub-GHz devices. This will add a tiny bit more
logic in L2 code for channel management. This option is automatically
selected when relevant device driver is enabled.
