[target/[msm7627,msm7630]: Add persist partition and re-arange partition table.
Move recovery partition to the end.
Add persist partition to msm7627_surf, msm7627_ffa and msm7630_surf targets.
Make userdata partition to have variable length and add code to
allocate the remaining/leftover space on flash to userdata partition.
Correct the density value for 4k page nand device in the supported nand
devices array.
Increase the system partition for msm7630_surf target by 5MB.
