LED2 is connected to MPP1_2 pin. It is working only on V7 boards.
V5 boards have hw bug which cause that LED2 is non-working.
So enable LED2 only for Espressobin V7 boards.
Note that LED1 is connected to LED_WLAN# pin on miniPCIe card and LED3 to
power supply. Therefore on Espressobin board only LED2 can be controlled
directly from the host. LED1 is possible to control via WiFi card inserted
in miniPCIe slot if driver for particular card supports it.

Previous version of this patch was sent by Uwe in March 2018, but it did
not work on any tested V5 board. Now we know it was due to V5 HW bug.

Hello! Gregory, I would like to remind you following patch.
Andre, if you have a time, could you test it too?

Hi Pali
Since the merge window is open at the moment, no new patches will be
accepted until it closes.
You should resend once -rc1 is out.

I would, but I desoldered all LEDs a long time ago because they're way
too bright...

No, problem, on V5 is needed just to check that led2 is not exported in sysfs.

Hello! -rc1 was already released. And as there are no new changes in
https://git.kernel.org/pub/scm/linux/kernel/git/gclement/mvebu.git/
repository since I sent this patch, I guess that I resending it not
needed.
