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 <yegorslists@googlemail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
