[PATCH v5 03/17] media: dt-bindings: renesas,rzg2l-cru: Document Renesas RZ/G3E SoC

The CRU block found on the Renesas RZ/G3E ("R9A09G047") SoC has five
interrupts:

- image_conv: image_conv irq
- axi_mst_err: AXI master error level irq
- vd_addr_wend: Video data AXI master addr 0 write end irq
- sd_addr_wend: Statistics data AXI master addr 0 write end irq
- vsd_addr_wend: Video statistics data AXI master addr 0 write end irq

This IP has only one input port 'port@1' similar to the RZ/G2UL CRU.

Document the CRU block found on the Renesas RZ/G3E ("R9A09G047") SoC.

Changes since v1:
- Use oneOf for interrupts and interrupt-names
- Handle interrupts and interrupt names base on soc variants

Changes since v2:
- Collected tag.
