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.
