libfdt: Introduce new ARCH_FIXUP_FDT option
Add new Kconfig option to disable arch_fixup_fdt() calls for cases where U-Boot shouldn't update memory setup in DTB file. One example of usage of this option is to boot OS with different memory setup than U-Boot use. Signed-off-by: Michal Simek <michal.simek@xilinx.com> Acked-by: Simon Glass <sjg@chromium.org>
