Add support for memory alignment requirements and adjust a candidate address to it before checking whether the block is large enough. This must be done in this order since the alignment adjustment can make a block smaller than what was requested. None of the current callers has memory alignment requirements but the ieee1275 loader for kernel and initrd will use it to convey them.
