[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj at bp.renesas.com>

Hi all,

This patch series aims to add SoC identification support for the Renesas
RZ/V2H SoC.

v1 - > v2
- Replaced RZ/V2H{P} -> RZ/V2H(P)
- Included Ack from Krzysztof for patch #1
- Included RB from Geert for patch #1 and #4
- Dropped extal_clk node from patch #2
- Used small case for hex value in patch #3

v1:
