[PATCH] arm64: zynqmp: Add support for u-boot.itb generation with ATF.

Follow i.MX, Sunxi, RISC-V and Rockchip to generate u-boot.itb which includes U-Boot proper, ATF and DTBs in FIT format. ZynqMP supports FIT for quite a long time but with using out of tree solution. The patch is filling this gap.
Tested on zcu102, zcu104 and zcu100/Ultra96.
