ARM/highbank: add support for Calxeda ECX-2000 / Midway 

The Calxeda ECX-2000 chip (aka. Midway) is model-wise quite similar
to the Highbank. The most prominent difference is the Cortex-A15 CPU
core in it, together with the associated core peripherals.

Add a new ARM machine type called "midway".
Move the L2 cache controller device into the Highbank specific part,
since Midway does not have (and need) it.
