[v4 16/17] arm: socfpga: soc64: Enable FIT image generation using binman

[Siew Chin Lim]

Add new build target "fit-itb" for FIT image generation.

In preparation to support Vendor Authorized Boot (VAB) for Intel
SOC64 device in near future. With VAB, u-boot proper, dtb and
arm trusted firmware need to be signed before FIT image generation.

To align user experience for ATF boot with and without VAB
feature, we skip binman for ARCH_SOCFPGA in default Makefile
flow. User always use 'make fit-itb' to generate FIT image
after successfully compile u-boot.
