We'll match on "soc" compatible for generic code, and "fsl,soc"

Unfortunately it's still impossible to remove device_type = "soc"
from the existing device tree, because older u-boots are looking for
it.

Neither we can remove model number from the soc name to heal
arch/powerpc/boot/cuboot-85xx.c, because then dts'es will be
incompatible with older u-boots again.

So, just one machine converted so far: MPC8360E-RDK. It's new machine
so we don't care about backward compatibility yet.

I know, this patch will conflict with the legacy serial rework[1].
It's okay though, if [1] will hit galak/powerpc.git first, I'll
simply rebase that patch.

this needs a bit more discussion.  "fsl,soc" is terrible describe.  I  
think we want some generic for the compat that implies 'soc register  
space'.
