fdt_support: skip MTD node with "disabled" in fdt_fixup_mtdparts()
Currently, fdt_fixup_mtdparts() only checks the compatible property. It is pointless to fix up the disabled node. Skip the node if it has the property: status = "disabled" Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org>
