The dtpm hierarchy can now be removed with the
dtpm_destroy_hierarchy() function. Add the module_exit() callback so
the module can be unloaded by removing the previously created
hierarchy.

The DTPM framework does support now the hierarchy description.
The platform specific code can call the hierarchy creation function
with an array of struct dtpm_node pointing to their parent.
This patch provides a description of the big / Little CPUs and the
GPU and tie them together under a virtual 'package' name. Only rk3399 is
described now.
The description could be extended in the future with the memory
controller with devfreq.
The description is always a module and it describes the soft
dependencies. The userspace has to load the softdeps module in the
right order.
