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.
