With commit d8e8fd0ebf8b ("mtd: rawnand: denali: decouple controller and NAND chips"), the Denali NAND controller driver migrated to the new controller/chip representation. Update DT for it. In the new binding, the number of connected chips are described in DT instead of run-time probed. I added just one chip to the reference boards, where we do not know if the on-board NAND device is a single chip or multiple chips. If we added too many chips into DT, it would end up with the timeout error in nand_scan_ident(). I changed all the pinctrl properties to use the single CS.
