[2/2] arm64: dts: renesas: rzv2l-smarc: Enable CRU, CSI support

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

Enable CRU, CSI on RZ/V2L SMARC EVK and tie the CSI to the OV5645 sensor
using Device Tree overlay. RZ/G2L SMARC EVK and RZ/V2L SMARC EVK have the
same connections for connecting the CSI to OV5645 sensor so just reuse
the existing r9a07g044l2-smarc-cru-csi-ov5645.dtso and create a symbolic
link to this file for RZ/V2L SMARC EVK.

Perhaps it makes more sense to rename r9a07g044l2-smarc-cru-csi-ov5645.dtso
to rzg2l-smarc-cru-csi-ov5645.dtso instead?

ok, and then for g2lc [0] I add rzg2lc-smarc-cru-csi-ov5645.dtso ?
