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.

Even when the IGEPv2 board and the IGEP Computer-on-Module
are different from a form factor point of view, they are
very similar in the fact that share many components and how
they are wired.

So, it is possible (and better) to have a single board file
for both devices and just use the CONFIG_MACH_TYPE to make
a differentiation between each board when needed.

This change avoids code duplication by removing 298 lines of
code and makes future maintenance easier.
