ARM: dts: am335x-baltos: add LED support

All three devices provide GPIO based LEDs named power, wlan and app. Place LEDs definition into a separate dtsi file as not all devices including am335x-baltos.dtsi have the same LED layout. Signed-off-by: Yegor Yefremov <[email protected]> Signed-off-by: Tony Lindgren <[email protected]>
