arm: spl: For Falcon Mode, set a default machid of ~0
With device trees, boards do not always set CONFIG_MACH_TYPE now, so we
must not rely on this define being set. The kernel uses ~0 to see if we
have a valid machine number or not, so set that as the default, invalid
machine, id and only fix if CONFIG_MACH_TYPE is set.
