fdt_resize(): fix actualsize calculations with unaligned blobs
The code in fdt_resize() to extend the fdt size to end on a page boundary
is wrong for fdt's not located at an address aligned on a page boundary.
What's even worse, the code would make actualsize shrink rather than grow
if (blob & 0xfff) was bigger than the amount of padding added by ALIGN(),
causing fdt_add_mem_rsv to fail.
Fix it by aligning end address (blob + size) to a page boundary instead.
For aligned fdt's this is equivalent to what we had before.
