[ARM] 3052/1: add ixp2000 microcode loader

Patch from Lennert Buytenhek

This patch adds a microcode loader for the ixp2000 architecture.

The ixp2000 is an xscale-based CPU with a number of additional small
CPUs ('microengines') on die that can be programmed to do various
things.  Depending on the ixp2000 model, there are between 2 and 16
microengines.

This code provides an API that allows configuring the microengines,
loading code into them, and starting and stopping them and reading
out a number of status registers, and is used by the microengine
network driver that was recently announced to netdev.
