Add IRQC node to R9A07G043 (RZ/G2UL) SoC DTSI.

Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>
---
Note,
- clocks and resets are differnt when compared to RZ/Five hence its added
  in r9a07g043u.dtsi
- We have additional interrupt on RZ/Five hence interrupts are added in
  r9a07g043u.dtsi
- clock-names is also added in r9a07g043u.dtsi to avoid dtbs_check warning

I missed this RZ/G2UL has this interrupt too. So ignore this point.

If we add the clock-names property in the base dtsi we get a
dtbs_check warning "clocks is a dependency of clock-names" for RZ/Five
as we haven't added the clocks property to it.

Agreed.
