Add initial support for RZ/N2H SoC and EVK

[PATCH v2 0/4] Add initial support for RZ/N2H SoC and EVK

Hi All,

This patch series adds initial support for the Renesas RZ/N2H SoC and
the RZ/N2H Evaluation Board (EVK). The series includes:
1. An initial SoC DTSI for the RZ/N2H SoC, which includes the basic
   configuration of the SoC blocks such as EXT CLKs, 4X CA55, SCIF,
   CPG, GIC, and ARMv8 Timer.
2. A new DTSI for the R9A09G087M44 variant of the RZ/N2H SoC, which
   features a 4-core configuration.
3. Refactoring of the RZ/T2H EVK device tree to extract common entries
   into a new file, `rzt2h-n2h-evk-common.dtsi`, to reduce
   duplication between the RZ/T2H and RZ/N2H EVK device trees.
4. An initial device tree for the RZ/N2H EVK, which includes
   the common entries from the previous step and sets up the board
   model and compatible strings.

Note,
- I've split up this patch from original series [1] to make it easier
  to review and apply.
- This patch series applied on top of the series [2].

[2] https://lore.kernel.org/all/20250617162810.154332-1-prabhakar.mahadev-lad.rj@bp.renesas.com/

v1->v2:
- Reordered the `l3_ca55` node and renamed it to `L3_CA55` for consistency
- Renamed the file to `rzt2h-n2h-evk-common.dtsi` to better reflect its
  purpose.
- Updated model string to "Renesas RZ/N2H EVK Board based on r9a09g087m44"
- Added reviewed-by tag from Geert

Cheers,
Prabhakar

Thank you, both [2] and this series are good to go, once the
updated renesas,rsci DT bindings are accepted.
