rockchip/soc/drivers: Add DTPM description for rk3399

Browse source

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.
