powercap/dtpm: Destroy hierarchy function
The hierarchy creation function exits but without a destroy hierarchy
function. Due to that, the modules creating the hierarchy can not be
unloaded properly because they don't have an exit callback.
Provide the dtpm_destroy_hierarchy() function to remove the previously
created hierarchy.
The function relies on all the release mechanisms implemented by the
underlying powercap framework.
