Michael Ellerman 8c20fafa85 [PATCH] powerpc: Make sure we don't create empty lmb regions
To prevent problems later in boot, make sure we don't create zero-size lmb
regions.

I've checked all the callers, and at the moment no one should ever hit this.
All callers use a constant size, or they check the computed size before they
call us.
