[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 Jan 2012:
   https://github.com/archlinuxarm/PKGBUILDs/pull/124
A similar patch is available for OpenWrt:
  http://patchwork.openwrt.org/patch/1412/
