[PATCH v3 17/18] arm64: dts: ti: k3-v3link: Add overlay for IMX219+UB953 serializer

[Yemike Abhilash Chandra <y-abhilashchandra@ti.com>]

From: Jianzhong Xu <xuj@ti.com>

Arducam V3Link camera solution is shipped with an UB953 serializer
and an IMX219 sensor [1]. Add an overlay for interfacing the UB953
serializer and IMX219 sensor with the RX0 port on the UB960 deserializer.

This overlay can be used to interface an IMX219 sensor on any platform
that supports the V3Link fusion board.

Changes in v3:
- Rename fixed-clock node to the generic clock-<frequency> form
  (Krzysztof)
- Also rename fixed-clock label to lowercase
- Drop underscores from regulator node names to follow upstream dts
  style (Krzysztof)
- Use GPL-2.0-only OR MIT license for consistency
- Update copyright year to 2026 (Udit)
