The IGEPv2 board has two user GPIO LEDs and one of them is default to "on" to tell the user that the board booted correctly. But to use these LEDs the config options CONFIG_LEDS_GPIO, CONFIG_LEDS_TRIGGERS and CONFIG_LEDS_TRIGGER_DEFAULT_ON have to be enabled. Since only the default-on and default-off triggers were used anyway, it is better to just use .default_state instead of .default_trigger and not depend on CONFIG_LEDS_TRIGGER_* Also, this is consistent with IGEPv2 Device Tree that uses default-state instead of linux,default-trigger for the leds device nodes. The LED names also have been updated to use the same names used on omap3-igep0020.dtb.
