ARM: dts: microchip: sama7g54_curiosity: Add fixed-partitions for spi-nor flash
Add fixed-partitions for spi-nor flash to match the at91 boot flow
and layout of the nand flash.
Partitions can be listed from /proc/mtd:
[root@sama7g54 ~]$ cat /proc/mtd | grep qspi
mtd6: 00040000 00001000 "qspi1: at91bootstrap"
mtd7: 00100000 00001000 "qspi1: u-boot"
mtd8: 00040000 00001000 "qspi1: u-boot env"
mtd9: 00080000 00001000 "qspi1: device tree"
mtd10: 00600000 00001000 "qspi1: kernel"
[root@sama7g54 ~]$ mtdinfo /dev/mtd10
mtd10
