This patch fixes the "sf probe" command. The very first SPI flash probe passes, for instance when u-boot tries to read its environment settings from a (Q)SPI memory but next "sf probe" commands fail because the flash memory node is unbound from the SPI controller children nodes.

The original code was to handle 'sf probe' where it actually creates a new ad-hoc device (not from the device tree). But I'm happy to drop this.
