clk: berlin: drop direct of_iomap of nodes reg property

The Berlin clock driver was sharing a DT node with the pin controller and the reset driver. All these devices are now sub-nodes of the chip controller. This patch rework the Berlin clock driver to allow moving the Berlin clock DT bindings into their own sub-node of the chip controller node.
