[U-Boot] [PATCH v3 6/8] fdt: cmd_fdt: Call fdt_chosen() from "fdt boardsetup"

[Stefan Roese]

By calling fdt_chosen(), the chosen node will be updated /
created by the "fdt boardsetup" command. This is useful for
setting of the kernel commandline via the "bootargs"
env variable.

With this change, the "fdt boardsetup" can be used to prepare
the DT blob for SPL booting. The patched DT blob can be saved
to flash and can be used by the SPL U-Boot version directly
for Linux booting.
