staging: greybus: arche-platform: fix OF populate on driver rebind

Browse Source 
Since commit c6e126de43 ("of: Keep track of populated platform
devices") child devices will not be created by of_platform_populate()
if the devices had previously been deregistered individually so that the
OF_POPULATED flag is still set in the corresponding OF nodes.

Switch to using of_platform_depopulate() instead of open coding so that
the child devices are created if the driver is rebound.

Fixes: bc142bbb4c ("greybus: arche_platform: Remove child's platform device as part of _remove() fn")
