[PATCH v2][POWERPC] Fix initial lmb add region with a non-zero base
If we add to an empty lmb region with a non-zero base we will not coalesce
the number of regions down to one. This causes problems on ppc32 for the
memory region as its assumed to only have one region.
We can fix this easily by causing the initial add to replace the dummy
region.

Fix a bug the initial patch introduced if we have a region that gets added
at the beginning of the list we wouldn't actually add it.
Dave can you replace the patch in you tree with this one.
