[PATCH master] sandbox: dts: skip reboot mode without hostfile

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The stickypage hostfile won't probe if the file is missing, yet because
it's compatible to simple-mfd, its child nodes will be probed and fail
their probe, because the hostfile itself was missing.

Fix this by only probing hostfile children if the parent probe concludes
successfully.
