The chip and system controller nodes are now handled by the Berlin

sub-nodes.

Rework the device tree to take this changes into account.

Antoine,

I noticed just now, but we should either have all of clock, reset,
pinctrl as sub-nodes or none. Currently, this has pinctrl and reset
as sub-nodes but clock hooked up to chip-controller.
