Use devm_of_platform_populate() instead of of_platform_populate and
of_platform_depopulate to simplify driver code

Hi Benjamin,

Same as patch 1, This is going to change order of sub devices removal.
It may end-up with bellow resources being removed while sub-device still
needs them.
Not sure this is a good candidate for such a change.

Best Regards,
Fabrice
