From: Lad Prabhakar <prabhakar.mahadev-lad.rj at bp.renesas.com>
Add the initial Device Tree Source Include (DTSI) file for the Renesas
RZ/V2N (R9A09G056) SoC. Include support for the following components:
- CPU (Cortex-A55 cores with operating points)
- External clocks (audio, qextal, rtxin)
- Pin controller (GPIO support)
- Clock Pulse Generator (CPG)
- System controller (SYS)
- Serial Communication Interface (SCIF)
- Secure Digital Host Interface (SDHI 0/1/2)
- Generic Interrupt Controller (GIC)
- ARMv8 timer

Note, dtbs_check complains about missing interrupt properties for pinctrl.
This is because, as part of the initial support, the ICU has not been
added yet. The interrupt-related properties will be added to the pinctrl
node along with ICU support.
