[v3 02/16] arm: socfpga: soc64: Load FIT image with ATF support

[Siew Chin Lim]

From: Chee Hong Ang <chee.hong.ang at intel.com>

Instead of loading u-boot proper image (u-boot.img), SPL
now loads FIT image (u-boot.itb) which includes u-boot
proper, ATF and u-boot proper's DTB.

For OS, u-boot now loads FIT images (kernel.itb) which
includes Linux Image and Linux's DTB.
