[U-Boot] [PATCH 5/5] moveconfig: Always run savedefconfig on the moved config

[Joe Hershberger]

This will ensure that the order of the defconfig entries will always
match that of the Kconfig files. After one slightly painful (but
still early in the process) pass over all boards, this should keep
the defconfigs clean from here on.
