dtpm/soc/rk3399: Add the ability to unload the module

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.

rockchip/soc/drivers: Add DTPM description for rk3399

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.
