[v5 16/18] arm: socfpga: dts: soc64: Add binman node of FIT image with ATF support

[Siew Chin Lim]

Add binman node to device tree to generate the FIT image for u-boot
(u-boot.itb) and OS kernel (kernel.itb).

u-boot.itb contains arm trusted firmware (ATF), u-boot proper and
u-boot device tree for ATF u-boot flow.

kernel.itb contains Linux Image and Linux device tree.

Change 'blob' to 'blob-ext' entry in binman dts node for all input files.
The input files (u-boot proper, Linux image files) that required to
build FIT images may not yet ready during u-boot compilation.
By using 'blob-ext', binman will report warning instead of error
during u-boot compilation when the input files doesn't exist.
It wouldn't fail the u-boot compilation. Then, user can prepare the
input files later, and use binman command to generate the FIT images.
