Emulators such as BDI2000 and CodeWarrior needs to have MSR_DE set

This adds MSR_DE for kernel space only.

I have tested this briefly with BDI2000 on P2010(e500) and
it works for me. I don't know if there are any bad side effects, therfore
this RFC.

I believe that additional patches are required for CodeWarrior to work
properly (e.g., assembly start up). I think the patches should come
from Freescale. For whatever reason, they include them in their SDK,
but haven't submitted them for inclusion in the mainline.
As a developer on Freescale Power products, I would like to see
Freescale offer up a CodeWarrior patch set, so I don't have to manage
the patches myself when working outside the SDK (i.e., on a more recent
kernel).
