OMAP3: igep00x0: add boot status GPIO LED
This patch adds an GPIO LED boot status for IGEP boards.
The GPIO LED used is the red LED0 while the Linux kernel
uses the green LED0 as the boot status.
By using different GPIO LEDs, the user can know in which
step of the boot process the board currently is.
