powerpc: Cleanup memblock usage
* early_init_devtree(): Total memory size is aligned to PAGE_SIZE;
however, alignment isn't enforced if memory_limit is explicitly
specified. Simplify the logic and always apply PAGE_SIZE alignment.
* MMU_init(): memblock regions is truncated by directly modifying
memblock.memory.cnt. This is incomplete (reserved array is not
truncated) and unnecessarily low level hindering further memblock
improvments. Use memblock_enforce_memory_limit() instead.
* wii_memory_fixups(): Unnecessarily low level direct manipulation of
memblock regions. The same result can be achieved using properly
abstracted operations. Reimplement using memblock API.
