IPU3: Missing INT3472 TPS68470 board-data quirk for Dell Latitude 5290 2-in-1

Hi all,

On a Dell Latitude 5290 2-in-1, the IPU3 stack initializes but the built-in MIPI
camera never appears in the media graph. The INT3472 TPS68470 glue driver logs:

  int3472-tps68470 i2c-INT3472:05: error -ENODEV: No board-data found for this model

As a result, no image sensor subdevice binds to ipu3-csi2/cio2, and libcamera
reports no cameras.

System:
  DMI sys_vendor:     Dell Inc.
  DMI product_name:   Latitude 5290 2-in-1
  DMI product_version:09WJPW
  DMI board_vendor:   Dell Inc.

Kernel:
  Ubuntu 24.04.2 (Noble)
  6.14.0-29-generic (OEM kernel), also reproduced on 6.14.0-27-generic

Relevant logs:
  [    4.062293] int3472-tps68470 i2c-INT3472:05: TPS68470 REVID: 0x21
  [    4.064758] int3472-tps68470 i2c-INT3472:05: error -ENODEV: No board-data found for this model
  [    4.231902] ipu3-imgu ... loaded firmware version irci_irci_ecr-master_20161208_0213_20170112_1500

Media graph (abridged):
  ipu3-csi2 N -> ipu3-cio2 N links are present,
  but no sensor subdevice (ov*/imx*) appears.

libcamera: v0.2.0 (IPU3 IPA present), `cam -l` yields no cameras.

Request:
  Please add the appropriate INT3472 TPS68470 board-data DMI quirk for this model
  so the PMIC and sensor can be configured and the sensor can bind.

I can provide:
  - Full dmesg/journal
  - `media-ctl -p`
  - `v4l2-ctl --list-devices`
  - ACPI dump (`acpidump.bin`)
  - Any further testing/patch verification
