[PATCH] Added support for pogoplug e02 (pink/gray)

[Christoph Junghans]

The pogoplug differs from the SheevaPlug only by a
few details, but especially in the led assignments.
This patch was tested under Gentoo Linux.
A version of this patch was included in Arch Linux
on Arm since Jun 2014:
https://github.com/archlinuxarm/PKGBUILDs/commit/250c2f0aa6ffe66c0ebda61efaa356e5dc709cc7
A similar patch is available for OpenWrt:
https://dev.openwrt.org/browser/trunk/target/linux/kirkwood/patches-3.14/150-pogoplug_e02.patch
