This patch adds a new machine ARCH_MXCM4 which requires !MMU and
!MULTIARCH and is meant as machine for the hetregenous multi-core
Vybrid/i.MX SoC's to run Linux on the Cortex-M4.

The first SoC supported is Vybrid on Cortex-M4 (SOC_VF610M4).

Not sure whether we really need a new MACH, but since MACH_MXC needs
MULTIARCH, which in turn conflicts with !MMU, I guess there is no
easier way to do it... And then, this also needs a new SOC.

I've carried an experimental patch to enable !MMU in combination with
MULTIPLATFORM for a while, it's probably time to do this for real now,
especially since we now have two !MMU platforms that can be built
together. Independent of the question of whether such a combined kernel
could run on real hardware or anybody would want to run such a kernel
if it were possible, I think it's very useful to be able to build
allmodconfig with MMU disabled and get all drivers for the available
platforms for build testing.
