lantiq: dts: assign the NAND pins to the nand-controller node
Assign the NAND pins to the NAND controller node instead of using pin hogging (where pins are assigned to the pin controller). This is the preferred way of assigning pins upstream. While here, define all NAND pins (CLE, ALE, read/RD, ready busy/RDY and CE/CS1). This means that the pinctrl subsystem knows that these pins are in use and cannot be re-assigned as GPIOs for example.
