[PATCH 2/3] staging: greybus: arche-platform: fix memleak on probe failure

[Johan Hovold <johan@kernel.org>]

Make sure to depopulate the child devices in case of late probe
failures to avoid leaking the corresponding resources.

Fixes: fd60ac585607 ("greybus: arche-platform: Fix boot, poweroff and fw_flashing seq with APBs")
