Filip Kokosinski 28c7674c66 dts/riscv: add `riscv` compatible string where it's missing
This commit adds the `riscv` compatible string to cpu nodes where it is
currently missing. This is convention is already followed by some cpu
nodes.

Filip Kokosinski 806c95163a dts/riscv: add missing `riscv,isa` fields and modify existing ones
This commit adds/modifies `riscv,isa` strings using the following rules:
* the ISA string is lowercase
* multi-letter extensions are preceded with the underscore mark
* if an extension is implied by another one, it is not specified - e.g. the
  D extension implies the F extension, so writing `rv32ifd` is redundant

Olof Johansson 07ac630281 dts: riscv: add #address-cells to all interrupt controllers
This mirrors #36499 and other PRs that added them for other
architectures.

This silences a large number of dtc warnings due to the missing
property. It seems reasonable to require an address-cells property since
any interrupt controller could be the parent of an interrupt-map.

The only device actually using interrupt-maps is neorv32, and it needs
an address-cells of 2 (since this is the default if none is specified it
worked like that before this change).

While I touched this, I reordered the properties for consistency across
boards, but there's a lot of variance here already.

Gerard Marull-Paretas 0d85931315 dts: migrate includes to <zephyr/...>
In order to bring consistency in-tree, migrate all dts code to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to zephyrproject-rtos#45388 for more details.

Henrik Brix Andersen b5d6f7f185 dts: riscv: neorv32: add gpio nodes
Add devicetree nodes for the NEORV32 GPIO device.

The GPIO port is 64 bits wide, but Zephyr only supports up to 32 bit
wide GPIO ports. The GPIO device is therefore handled as two Zephyr GPIO
devices with a nexus devicetree node mapping pins 0 to 31 to the device
handling the lower half, and pins 32 to 63 to the device handling the
upper half.
