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

Document RZ/G2UL (R9A07G043) IRQC bindings. The RZ/G2UL IRQC block is
identical to one found on the RZ/G2L SoC. No driver changes are
required as generic compatible string "renesas,rzg2l-irqc" will be
used as a fallback.

Note, renesas,r9a07g043u-irqc is added we have slight difference's compared to RZ/Five
- G2UL IRQCHIP (hierarchical IRQ domain) -> GIC where as on RZ/Five we have PLIC (chained interrupt
domain) -> RISCV INTC
- On the RZ/Five we have additional registers for IRQC block
- On the RZ/Five we have BUS_ERR_INT which needs to be handled by IRQC
