Change module build sequence. 1. Get FvImageName list according to their declaration order in the fpd file. 2. First build all modules in the first fvimage, then build all modules in the second fvimage, and so on. These modules sequence is still from their layout in the fpd file. 3. At last, build the remaining modules whose FVBinding = NULL. And also clean some unused code, and add and update some comments.
