This is version 3 of Devres series.
Simon, Albert and I discussed whether we need (and want) to get this framework in.
Looks like our agreement is that we can add Devres, but keeping it optional. The DM core part still sticks to the manual malloc() and free().
With CONFIG_DEVRES disabled, devres APIs fall back to normal memory allocators, so there is no overhead.
