Support for multi-stream in j721e-csi2rx.c driver was merged last cycle[0].
This series adds the corresponding device tree support.

Patch 1 is a cleanup fixing indentation in the existing CSI2RX nodes.

The next few patches i.e. (Patch 2 to Patch 6) add the additional DMA
channels required for CSI2RX multi-stream capture.

Multi-stream capture uses a SERDES pair based on the FPD-Link or
V3Link protocol. The serializer takes the input from a camera sensor
and converts it to the FPD-Link standard, while the deserializer
aggregates streams from multiple serializers and sends them over the
CSI-2 RX interface. Each CSI2RX instance therefore indirectly receives
input from multiple sensors.

The remaining patches add overlays for various deserializer boards,
and for the UB953 serializer with the IMX219 sensor. Also enabling
DS90UB960 deserializer and DS90UB953 serializer drivers in the
arm64 defconfig.

Changelog:
Changes in v2:
- Add missing bus-type property in csi2_phy endpoints in overlays (sashiko)
- Add missing build targets in Makefile for some overlays (sashiko)
- Fix minor DTS styling and whitespace inconsistencies in port definitions in overlays (sashiko)
- Remove unused gpio.h header in overlays (sashiko)
- Don't replacing generic V3Link fusion board DTB targets instead append new build
  targets for v3link + IMX219 (sashiko) (Patch 17)
- Add status = "okay" property in port 0 of deserializer ports (sashiko) (patch 17)
- Add port-specific suffixes to avoid naming collisions (sashiko) (patch 17)
- Add reason in the commit message on why we want the DS90UB960 deserializer and DS90UB953
  serializer drivers to be enabled in defconfig (Krzysztof) (Patch 18)
- Rebase on top of linux-next (20260709)
