[U-Boot] [PATCH v2 3/9] fdt_support: delete force argument of fdt_initrd()

[Masahiro Yamada]

After all, we have realized "force" argument is completely
useless. fdt_initrd() was always called with force = 1.

We should always want to do the same thing
(set appropriate value to the property)
even if the property already exists.
