memblock: Remove rmo_size, burry it in arch/powerpc where it belongs
The RMA (RMO is a misnomer) is a concept specific to ppc64 (in fact server ppc64 though I hijack it on embedded ppc64 for similar purposes) and represents the area of memory that can be accessed in real mode (aka with MMU off), or on embedded, from the exception vectors (which is bolted in the TLB) which pretty much boils down to the same thing. We take that out of the generic MEMBLOCK data structure and move it into arch/powerpc where it belongs, renaming it to "RMA" while at it.
