[PATCH] soc: qcom: geni: depopulate children on populate failure

[Pengpeng Hou <pengpeng@iscas.ac.cn>]

devm_of_platform_populate() installs its devres cleanup action only after
of_platform_populate() succeeds.  If child population fails after creating
some GENI children, those partial children are not automatically removed
by devres because the action was never added.

Depopulate the children explicitly when devm_of_platform_populate()
returns an error.
