We should only perform additional iteration steps when needed to initialize the parent of a device. Other binding errors (such as a missing driver) should not lead to additional iteration steps.
Unnecessary iteration steps can cause issues when memory is tightly constrained (such as in the TPL/SPL) since device_bind_by_name() unconditionally allocates memory for a struct udevice. On the SanCloud BBE this led to boot failure caused by memory exhaustion in the SPL when booting from SPI flash.

For the series, applied to u-boot/master, thanks!
