When dtb is padded in the end of U-Boot binary, dtb should always be relocated whether GD_FLG_SKIP_RELOC set or not, otherwise dtb maybe corrupted.

Need copy old gd contents to new_gd area, this may not needed on x86 or arc, but needed for ARM64, because crt0_64.S points x18 to new_gd, considering gd is a small area, and common/board_f.c also use new_gd, so let's always copy it.

Have a look at these patches:
