ARM: OMAP3: igep0020: simplify GPIO LEDs dependencies

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.
