[PATCH 04/12] mach-sc5xx: Add preliminary support for binman

[Greg Malysa <malysagreg@gmail.com>]

From: Utsav Agarwal <utsav.agarwal@analog.com>

Binman is optionally supported for Analog Devices sc5xx SoCs if Yocto is
not being used to create and assemble system images. The spl LDR is
generated locally but other artifacts such as kernel FIT image and root
file system are built externally and must be supplied to binman if used.

Binman is enabled by selecting the SC5XX_USE_BINMAN config symbol and
the image structure is included in the shared sc5xx device tree.
