Generate 'u-boot-splx4.sfp' which consist of 4 SPL images required for booting up Cyclone5/Arria10.
By default, this 'u-boot-splx4.sfp' is generated without extra padding after each SPL image.
For Cyclone5, 'u-boot-splx4.sfp' contains: 4 x SPL(64KB) = 256KB
For Arria10, 'u-boot-splx4.sfp' contains: 4 x SPL(256KB) = 1024KB
For Cyclone5 using NAND flash image layout for 128 KB memory blocks, user can 'make' the following target to generate 4 SPL images with padding:
make u-boot-spl-padx4.sfp
'u-boot-spl-padx4.sfp' contains four 128KB SPL images (each 64KB SPL is followed by 64KB of zero-padding). 4 x (SPL(64KB) + zero-padding(64KB)) = 512KB

v3 changes:
- add 'u-boot-splx4.sfp' make target (4 x SPL image without paddings)
- add 'u-boot-spl-padx4.sfp' make target (4 x SPL image with 64KB paddings)
- Update commit message (refer to commit message for details explanation)
