w2914ns-v2, 11acnas, and freezio use almost same board and thus share a
common dtsi file. Now that LED labels do not contain "devicename" since
commit c846dd91f0 ("ramips: remove model name from LED labels"), let's
move the leds nodes to dtsi and remove them from dts.
Note that freezio has only one USB 3.0 port and adding &ehci_port2 trigger
does not incur any visible changes.
