An allowance of 5 MiB for BSS is not enough for Linux kernels with certain
debug options enabled (not sure exactly which one caused it, but I'd guess
lockdep). The kernel I ran into this with had a BSS of around 6.4 MB.
Unfortunately, uImage does not give us enough information to determine the
actual BSS size. Increase the allowance to 18 MiB to give us plenty of
room. Eventually this should be more intelligent, possibly packing
initrd+dtb at the end of guest RAM.

The dumpdtb code can be useful in more places than just for e500. Move it
to a generic place.

This reverts commit 518c7fb44f2182cde943dc64f88cb2fd4e4ff6b5. It breaks
new Linux guests with SMP, because IPIs get mapped to large vectors which
our MPIC emulation does not implement.

Currently the only mpc8544ds-ism that is factored out is
toplevel compatible and model. In the future the generic e500
code is expected to become more generic.

No functional changes -- machine is still outwardly mpc8544ds.
The references that are not changed contain mpc8544 hardware details that
need to be parameterized if/when a different e500 platform wants to
change them.

Rename the file (with no changes other than fixing up the header paths)
in preparation for refactoring into a generic e500 platform. Also move
it into the newly created ppc/ directory.
