cbmem: Always maintain backing store struct in a global on non-x86
The current CBMEM code contains an optimization that maintains the structure with information about the CBMEM backing store in a global variable, so that we don't have to recover it from cbmem_top() again every single time we access CBMEM. However, due to the problems with using globals in x86 romstage, this optimization has only been enabled in ramstage. However, all non-x86 platforms are SRAM-based (at least for now) and can use globals perfectly fine in earlier stages. Therefore, this patch extends the optimization on those platforms to all stages. This also allows us to remove the requirement that cbmem_top() needs to return NULL before its backing store has been initialized from those boards, since the CBMEM code can now keep track of whether it has been initialized by itself.
