omap3beagle: add a platform device to hook up the GPIO leds to the leds-gpio driver
 * on revision A5 and earlier board the two leds can't be controlled seperately, should be fixed in rev. B and C boards.

Just one nitpicking cosmetic comment.. Can you please reformat the led structs
above using the standard Linux way with tabs:

...
	{
		.name			= "beagleboard::led0",
		.default_trigger	= "none",
		.gpio			= 149,
	},
...

Thanks,

Tony
