Hi All,

This patch series aims to split up the RZ/G2UL SoC DTSI into common parts
so that this can be shared with the RZ/Five SoC.

Implementation is based on the discussion [0] where I have used option#2.

The Renesas RZ/G2UL (ARM64) and RZ/Five (RISC-V) have almost the same
identical blocks to avoid duplication a base SoC dtsi (r9a07g043.dtsi) is
created which will be used by the RZ/G2UL (r9a07g043u.dtsi) and RZ/Five
(r9a07g043F.dtsi)

Sending this as an RFC to get some feedback.

r9a07g043f.dtsi will look something like below:

#include <dt-bindings/interrupt-controller/irq.h>

#define SOC_PERIPHERAL_IRQ_NUMBER(nr)	(nr + 32)
#define SOC_PERIPHERAL_IRQ(nr, na)	SOC_PERIPHERAL_IRQ_NUMBER(nr) na

#include <arm64/renesas/r9a07g043.dtsi>

/ {
   ...
   ...   
};

Although patch#2 can be merged into patch#1 just wanted to keep them separated
for easier review.
