I have not seen firmware builds which handle 'is it LTS or not' version 
of board.

The non-LTS version has usb20_host_pwren line not connected. So enabling 
it does not affect the board. Similar to 4g_lte_pwren line which is 
present on NanoPC-T6 non-LTS and not connected on LTS one.

Looks like vendor took care to keep both versions of board to work with 
one DT.
