I'm afraid I find this overly complex for the task.
If we choose to describe these groups of resources like you have done
here I see no point in having the SRM core.
You could just make the SRM devices platform_drivers that acquire
handles to the resources, register (early) subdevices to get the callback
on boot/shutdown and call enable/disable on the resources there.
