Enable CRU, CSI on RZ/G2UL SMARC EVK and tie the CSI to the OV5645 sensor
using Device Tree overlay.

 * This patch has a functional dependecy [1]
   [1] https://lore.kernel.org/all/20240213140240.159057-1-biju.das.jz@bp.renesas.com/
v2->v3:
 * Added missing r9a07g043u11-smarc-cru-csi-ov5645.dtbo entry in Makefile.
 * Made this as separate patch as SoC dtsi is accepted and dropping the
   i2c workaround patch for ov5645.
v1->v2:
 * No change.
