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

Align with the datasheet by adding regulator-5v which
supplies each node from the regulator using phandle to
regulator-5v through pvin[1-4]-supply and lvin-supply.

regulator-suspend-voltage with the valid property
By checking the pmic node with microchip,mcp16502.yaml#
'regulator-suspend-voltage' does not match any of the
regexes 'pinctrl-[0-9]+' from schema microchip,mcp16502.yaml#
which inherits regulator.yaml#. So replace regulator-suspend-voltage
with regulator-suspend-microvolt to avoid the inconsitency.
