ARM: dts: at91: sam9x60-curiosity: Add raw NAND flash

Browse source 
Basically the same as on sam9x60-ek.  Same as in Linux.  NAND flash is
correctly detected when booting into U-Boot:

    U-Boot 2023.07-rc6-00005-g12719f75dc-dirty (Jul 05 2023 - 13:06:35 +0000)

    Crystal frequency:       24 MHz

    Master clock     :      200 MHz

    Model: Microchip SAM9X60 Curiosity
