mkimage: Pad DTBs to target-specific pointer size

Browse source 
Device tree (DTB) lengths are being padded to a multiple of 4 bytes
rather than the target-specific pointer size. This causes objects
following OBJ_TYPE_DTB objects to be incorrectly parsed during GRUB
execution on arm64.

Fix by using ALIGN_ADDR(), not ALIGN_UP().
